+		3.1:  Spaces
+
+Linux kernel style for use of spaces depends (mostly) on
+function-versus-keyword usage.  Use a space after (most) keywords.  The
+notable exceptions are sizeof, typeof, alignof, and __attribute__, which look
+somewhat like functions (and are usually used with parentheses in Linux,
+although they are not required in the language, as in: "sizeof info" after
+"struct fileinfo info;" is declared).
+
+So use a space after these keywords:
+	if, switch, case, for, do, while
+but not with sizeof, typeof, alignof, or __attribute__.  E.g.,
+	s = sizeof(struct file);
+
+Do not add spaces around (inside) parenthesized expressions.  This example is
+*bad*:
+
+	s = sizeof( struct file );
+
+When declaring pointer data or a function that returns a pointer type, the
+preferred use of '*' is adjacent to the data name or function name and not
+adjacent to the type name.  Examples:
+
+	char *linux_banner;
+	unsigned long long memparse(char *ptr, char **retptr);
+	char *match_strdup(substring_t *s);
+
+Use one space around (on each side of) most binary and ternary operators,
+such as any of these:
+
+	=  +  -  <  >  *  /  %  |  &  ^  <=  >=  ==  !=  ?  :
+
+but no space after unary operators:
+	&  *  +  -  ~  !  sizeof  typeof  alignof  __attribute__  defined
+
+no space before the postfix increment & decrement unary operators:
+	++  --
+
+no space after the prefix increment & decrement unary operators:
+	++  --

+and no space around the '.' and "->" structure member operators.

+Devres - Managed Device Resource
+================================
+
+Tejun Heo	<teheo@suse.de>
+
+First draft	10 January 2007
+
+
+1. Intro			: Huh? Devres?
+2. Devres			: Devres in a nutshell
+3. Devres Group			: Group devres'es and release them together
+4. Details			: Life time rules, calling context, ...
+5. Overhead			: How much do we have to pay for this?
+6. List of managed interfaces	: Currently implemented managed interfaces
+
+
+  1. Intro
+  --------
+
+devres came up while trying to convert libata to use iomap.  Each
+iomapped address should be kept and unmapped on driver detach.  For
+example, a plain SFF ATA controller (that is, good old PCI IDE) in
+native mode makes use of 5 PCI BARs and all of them should be
+maintained.
+
+As with many other device drivers, libata low level drivers have
+sufficient bugs in ->remove and ->probe failure path.  Well, yes,
+that's probably because libata low level driver developers are lazy
+bunch, but aren't all low level driver developers?  After spending a
+day fiddling with braindamaged hardware with no document or
+braindamaged document, if it's finally working, well, it's working.
+
+For one reason or another, low level drivers don't receive as much
+attention or testing as core code, and bugs on driver detach or
+initilaization failure doesn't happen often enough to be noticeable.
+Init failure path is worse because it's much less travelled while
+needs to handle multiple entry points.
+
+So, many low level drivers end up leaking resources on driver detach
+and having half broken failure path implementation in ->probe() which
+would leak resources or even cause oops when failure occurs.  iomap
+adds more to this mix.  So do msi and msix.
+
+
+  2. Devres
+  ---------
+
+devres is basically linked list of arbitrarily sized memory areas
+associated with a struct device.  Each devres entry is associated with
+a release function.  A devres can be released in several ways.  No
+matter what, all devres entries are released on driver detach.  On
+release, the associated release function is invoked and then the
+devres entry is freed.
+
+Managed interface is created for resources commonly used by device
+drivers using devres.  For example, coherent DMA memory is acquired
+using dma_alloc_coherent().  The managed version is called
+dmam_alloc_coherent().  It is identical to dma_alloc_coherent() except
+for the DMA memory allocated using it is managed and will be
+automatically released on driver detach.  Implementation looks like
+the following.
+
+  struct dma_devres {
+	size_t		size;
+	void		*vaddr;
+	dma_addr_t	dma_handle;
+  };
+
+  static void dmam_coherent_release(struct device *dev, void *res)
+  {
+	struct dma_devres *this = res;
+
+	dma_free_coherent(dev, this->size, this->vaddr, this->dma_handle);
+  }
+
+  dmam_alloc_coherent(dev, size, dma_handle, gfp)
+  {
+	struct dma_devres *dr;
+	void *vaddr;
+
+	dr = devres_alloc(dmam_coherent_release, sizeof(*dr), gfp);
+	...
+
+	/* alloc DMA memory as usual */
+	vaddr = dma_alloc_coherent(...);
+	...
+
+	/* record size, vaddr, dma_handle in dr */
+	dr->vaddr = vaddr;
+	...
+
+	devres_add(dev, dr);
+
+	return vaddr;
+  }
+
+If a driver uses dmam_alloc_coherent(), the area is guaranteed to be
+freed whether initialization fails half-way or the device gets
+detached.  If most resources are acquired using managed interface, a
+driver can have much simpler init and exit code.  Init path basically
+looks like the following.
+
+  my_init_one()
+  {
+	struct mydev *d;
+
+	d = devm_kzalloc(dev, sizeof(*d), GFP_KERNEL);
+	if (!d)
+		return -ENOMEM;
+
+	d->ring = dmam_alloc_coherent(...);
+	if (!d->ring)
+		return -ENOMEM;
+
+	if (check something)
+		return -EINVAL;
+	...
+
+	return register_to_upper_layer(d);
+  }
+
+And exit path,
+
+  my_remove_one()
+  {
+	unregister_from_upper_layer(d);
+	shutdown_my_hardware();
+  }
+
+As shown above, low level drivers can be simplified a lot by using
+devres.  Complexity is shifted from less maintained low level drivers
+to better maintained higher layer.  Also, as init failure path is
+shared with exit path, both can get more testing.
+
+
+  3. Devres group
+  ---------------
+
+Devres entries can be grouped using devres group.  When a group is
+released, all contained normal devres entries and properly nested
+groups are released.  One usage is to rollback series of acquired
+resources on failure.  For example,
+
+  if (!devres_open_group(dev, NULL, GFP_KERNEL))
+	return -ENOMEM;
+
+  acquire A;
+  if (failed)
+	goto err;
+
+  acquire B;
+  if (failed)
+	goto err;
+  ...
+
+  devres_remove_group(dev, NULL);
+  return 0;
+
+ err:
+  devres_release_group(dev, NULL);
+  return err_code;
+
+As resource acquision failure usually means probe failure, constructs
+like above are usually useful in midlayer driver (e.g. libata core
+layer) where interface function shouldn't have side effect on failure.
+For LLDs, just returning error code suffices in most cases.
+
+Each group is identified by void *id.  It can either be explicitly
+specified by @id argument to devres_open_group() or automatically
+created by passing NULL as @id as in the above example.  In both
+cases, devres_open_group() returns the group's id.  The returned id
+can be passed to other devres functions to select the target group.
+If NULL is given to those functions, the latest open group is
+selected.
+
+For example, you can do something like the following.
+
+  int my_midlayer_create_something()
+  {
+	if (!devres_open_group(dev, my_midlayer_create_something, GFP_KERNEL))
+		return -ENOMEM;
+
+	...
+
+	devres_close_group(dev, my_midlayer_something);
+	return 0;
+  }
+
+  void my_midlayer_destroy_something()
+  {
+	devres_release_group(dev, my_midlayer_create_soemthing);
+  }
+
+
+  4. Details
+  ----------
+
+Lifetime of a devres entry begins on devres allocation and finishes
+when it is released or destroyed (removed and freed) - no reference
+counting.
+
+devres core guarantees atomicity to all basic devres operations and
+has support for single-instance devres types (atomic
+lookup-and-add-if-not-found).  Other than that, synchronizing
+concurrent accesses to allocated devres data is caller's
+responsibility.  This is usually non-issue because bus ops and
+resource allocations already do the job.
+
+For an example of single-instance devres type, read pcim_iomap_table()
+in lib/iomap.c.
+
+All devres interface functions can be called without context if the
+right gfp mask is given.
+
+
+  5. Overhead
+  -----------
+
+Each devres bookkeeping info is allocated together with requested data
+area.  With debug option turned off, bookkeeping info occupies 16
+bytes on 32bit machines and 24 bytes on 64bit (three pointers rounded
+up to ull alignment).  If singly linked list is used, it can be
+reduced to two pointers (8 bytes on 32bit, 16 bytes on 64bit).
+
+Each devres group occupies 8 pointers.  It can be reduced to 6 if
+singly linked list is used.
+
+Memory space overhead on ahci controller with two ports is between 300
+and 400 bytes on 32bit machine after naive conversion (we can
+certainly invest a bit more effort into libata core layer).

+	Format: <percent>
+
+	Note that one-failure-per-hundred is a very high error rate
+	for some testcases.  Consider setting probability=100 and configure
+	/debug/fail*/interval for such testcases.
+
+- /debug/fail*/interval:
+
+	specifies the interval between failures, for calls to
+	should_fail() that pass all the other tests.
+
+	Note that if you enable this, by setting interval>1, you will
+	probably want to set probability=100.
+
+- /debug/fail*/times:
+
+	specifies how many times failures may happen at most.
+	A value of -1 means "no limit".
+
+- /debug/fail*/space:
+
+	specifies an initial resource "budget", decremented by "size"
+	on each call to should_fail(,size).  Failure injection is
+	suppressed until "space" reaches zero.
+
+- /debug/fail*/verbose
+
+	Format: { 0 | 1 | 2 }
+	specifies the verbosity of the messages when failure is
+	injected.  '0' means no messages; '1' will print only a single
+	log line per failure; '2' will print a call trace too -- useful
+	to debug the problems revealed by fault injection.
+
+- /debug/fail*/task-filter:
+
+	Format: { 'Y' | 'N' }
+	A value of 'N' disables filtering by process (default).
+	Any positive value limits failures to only processes indicated by
+	/proc/<pid>/make-it-fail==1.
+
+- /debug/fail*/require-start:
+- /debug/fail*/require-end:
+- /debug/fail*/reject-start:
+- /debug/fail*/reject-end:
+
+	specifies the range of virtual addresses tested during
+	stacktrace walking.  Failure is injected only if some caller
+	in the walked stacktrace lies within the required range, and
+	none lies within the rejected range.
+	Default required range is [0,ULONG_MAX) (whole of virtual address space).
+	Default rejected range is [0,0).
+
+- /debug/fail*/stacktrace-depth:
+
+	specifies the maximum stacktrace depth walked during search
+	for a caller within [require-start,require-end) OR
+	[reject-start,reject-end).
+
+- /debug/fail_page_alloc/ignore-gfp-highmem:
+
+	Format: { 'Y' | 'N' }
+	default is 'N', setting it to 'Y' won't inject failures into
+	highmem/user allocations.
+
+- /debug/failslab/ignore-gfp-wait:
+- /debug/fail_page_alloc/ignore-gfp-wait:
+
+	Format: { 'Y' | 'N' }
+	default is 'N', setting it to 'Y' will inject failures
+	only into non-sleep allocations (GFP_ATOMIC allocations).
+
+o Boot option
+
+In order to inject faults while debugfs is not available (early boot time),
+use the boot option:
+
+	failslab=
+	fail_page_alloc=
+	fail_make_request=<interval>,<probability>,<space>,<times>
+
+How to add new fault injection capability
+-----------------------------------------
+
+o #include <linux/fault-inject.h>
+
+o define the fault attributes
+
+  DECLARE_FAULT_INJECTION(name);
+
+  Please see the definition of struct fault_attr in fault-inject.h
+  for details.
+
+o provide a way to configure fault attributes
+
+- boot option
+
+  If you need to enable the fault injection capability from boot time, you can
+  provide boot option to configure it. There is a helper function for it:
+
+	setup_fault_attr(attr, str);
+
+- debugfs entries
+
+  failslab, fail_page_alloc, and fail_make_request use this way.
+  Helper functions:
+
+	init_fault_attr_entries(entries, attr, name);
+	void cleanup_fault_attr_entries(entries);
+
+- module parameters
+
+  If the scope of the fault injection capability is limited to a
+  single kernel module, it is better to provide module parameters to
+  configure the fault attributes.
+
+o add a hook to insert failures
+
+  Upon should_fail() returning true, client code should inject a failure.
+
+	should_fail(attr, size);
+

+
+Fan Control
+-----------
+
+Both PWM (pulse-width modulation) and DC fan speed control methods are
+supported. The right one to use depends on external circuitry on the
+motherboard, so the driver assumes that the BIOS set the method
+properly. The driver will report the method, but won't let you change
+it.
+
+When the PWM method is used, you can select the operating frequency,
+from 187.5 kHz (default) to 31 Hz. The best frequency depends on the
+fan model. As a rule of thumb, lower frequencies seem to give better
+control, but may generate annoying high-pitch noise. Fintek recommends
+not going below 1 kHz, as the fan tachometers get confused by lower
+frequencies as well.
+
+When the DC method is used, Fintek recommends not going below 5 V, which
+corresponds to a pwm value of 106 for the driver. The driver doesn't
+enforce this limit though.
+
+Three different fan control modes are supported:
+
+* Manual mode
+  You ask for a specific PWM duty cycle or DC voltage.
+
+* Fan speed mode
+  You ask for a specific fan speed. This mode assumes that pwm1
+  corresponds to fan1, pwm2 to fan2 and pwm3 to fan3.
+
+* Temperature mode
+  You define 3 temperature/fan speed trip points, and the fan speed is

+
+
+Description
+-----------
+
+The National Semiconductor Super I/O chip includes complete hardware
+monitoring capabilities. It can monitor up to 18 voltages, 8 fans and
+6 temperature sensors. Only the fans are supported at the moment.
+
+This chip also has fan controlling features, which are not yet supported
+by this driver either.
+
+The driver assumes that no more than one chip is present, which seems
+reasonable.
+
+
+Fan Monitoring
+--------------
+
+Fan rotation speeds are reported as 14-bit values from a gated clock
+signal. Speeds down to 83 RPM can be measured.
+
+An alarm is triggered if the rotation speed drops below a programmable
+limit. Another alarm is triggered if the speed is too low to to be measured
+(including stalled or missing fan).

+  0x4a and 0x4b.
+
+
+Description
+-----------
+
+This driver implements support for Winbond W83793G/W83793R chips.
+
+* Exported features
+  This driver exports 10 voltage sensors, up to 12 fan tachometer inputs,
+  6 remote temperatures, up to 8 sets of PWM fan controls, SmartFan
+  (automatic fan speed control) on all temperature/PWM combinations, 2
+  sets of 6-pin CPU VID input.
+
+* Sensor resolutions
+  If your motherboard maker used the reference design, the resolution of
+  voltage0-2 is 2mV, resolution of voltage3/4/5 is 16mV, 8mV for voltage6,
+  24mV for voltage7/8. Temp1-4 have a 0.25 degree Celsius resolution,
+  temp5-6 have a 1 degree Celsiis resolution.
+
+* Temperature sensor types
+  Temp1-4 have 2 possible types. It can be read from (and written to)
+  temp[1-4]_type.
+  - If the value is 3, it starts monitoring using a remote termal diode
+    (default).
+  - If the value is 6, it starts monitoring using the temperature sensor
+    in Intel CPU and get result by PECI.
+  Temp5-6 can be connected to external thermistors (value of
+  temp[5-6]_type is 4).
+
+* Alarm mechanism
+  For voltage sensors, an alarm triggers if the measured value is below
+  the low voltage limit or over the high voltage limit.
+  For temperature sensors, an alarm triggers if the measured value goes
+  above the high temperature limit, and wears off only after the measured
+  value drops below the hysteresis value.
+  For fan sensors, an alarm triggers if the measured value is below the
+  low speed limit.
+
+* SmartFan/PWM control
+  If you want to set a pwm fan to manual mode, you just need to make sure it
+  is not controlled by any temp channel, for example, you want to set fan1
+  to manual mode, you need to check the value of temp[1-6]_fan_map, make
+  sure bit 0 is cleared in the 6 values. And then set the pwm1 value to
+  control the fan.
+
+  Each temperature channel can control all the 8 PWM outputs (by setting the
+  corresponding bit in tempX_fan_map), you can set the temperature channel
+  mode using temp[1-6]_pwm_enable, 2 is Thermal Cruise mode and 3
+  is the SmartFanII mode. Temperature channels will try to speed up or
+  slow down all controlled fans, this means one fan can receive different
+  PWM value requests from different temperature channels, but the chip
+  will always pick the safest (max) PWM value for each fan.
+
+  In Thermal Cruise mode, the chip attempts to keep the temperature at a
+  predefined value, within a tolerance margin. So if tempX_input >
+  thermal_cruiseX + toleranceX, the chip will increase the PWM value,
+  if tempX_input < thermal_cruiseX - toleranceX, the chip will decrease
+  the PWM value. If the temperature is within the tolerance range, the PWM
+  value is left unchanged.
+
+  SmartFanII works differently, you have to define up to 7 PWM, temperature
+  trip points, defining a PWM/temperature curve which the chip will follow.
+  While not fundamentally different from the Thermal Cruise mode, the
+  implementation is quite different, giving you a finer-grained control.
+
+* Chassis
+  If the case open alarm triggers, it will stay in this state unless cleared
+  by any write to the sysfs file "chassis".
+
+* VID and VRM
+  The VRM version is detected automatically, don't modify the it unless you
+  *do* know the cpu VRM version and it's not properly detected.
+
+
+Notes
+-----
+
+  Only Fan1-5 and PWM1-3 are guaranteed to always exist, other fan inputs and
+  PWM outputs may or may not exist depending on the chip pin configuration.

 0. Structure of PCI drivers
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
-There exist two kinds of PCI drivers: new-style ones (which leave most of
-probing for devices to the PCI layer and support online insertion and removal
-of devices [thus supporting PCI, hot-pluggable PCI and CardBus in a single
-driver]) and old-style ones which just do all the probing themselves. Unless
-you have a very good reason to do so, please don't use the old way of probing
-in any new code. After the driver finds the devices it wishes to operate
-on (either the old or the new way), it needs to perform the following steps:
+PCI drivers "discover" PCI devices in a system via pci_register_driver().
+Actually, it's the other way around. When the PCI generic code discovers
+a new device, the driver with a matching "description" will be notified.
+Details on this below.
+
+pci_register_driver() leaves most of the probing for devices to
+the PCI layer and supports online insertion/removal of devices [thus
+supporting hot-pluggable PCI, CardBus, and Express-Card in a single driver].
+pci_register_driver() call requires passing in a table of function
+pointers and thus dictates the high level structure of a driver.
+
+Once the driver knows about a PCI device and takes ownership, the
+driver generally needs to perform the following initialization:
 
 	Enable the device
-	Access device configuration space
-	Discover resources (addresses and IRQ numbers) provided by the device
-	Allocate these resources
-	Communicate with the device
+	Request MMIO/IOP resources
+	Set the DMA mask size (for both coherent and streaming DMA)
+	Allocate and initialize shared control data (pci_allocate_coherent())
+	Access device configuration space (if needed)
+	Register IRQ handler (request_irq())
+	Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
+	Enable DMA/processing engines
+
+When done using the device, and perhaps the module needs to be unloaded,
+the driver needs to take the follow steps:
+	Disable the device from generating IRQs
+	Release the IRQ (free_irq())
+	Stop all DMA activity
+	Release DMA buffers (both streaming and coherent)
+	Unregister from other subsystems (e.g. scsi or netdev)
+	Release MMIO/IOP resources
 	Disable the device
 
-Most of these topics are covered by the following sections, for the rest
-look at <linux/pci.h>, it's hopefully well commented.
+Most of these topics are covered in the following sections.
+For the rest look at LDD3 or <linux/pci.h> .
 
 If the PCI subsystem is not configured (CONFIG_PCI is not set), most of

-empty or just returning an appropriate error codes to avoid lots of ifdefs

-3. Enabling and disabling devices
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-   Before you do anything with the device you've found, you need to enable
-it by calling pci_enable_device() which enables I/O and memory regions of
-the device, allocates an IRQ if necessary, assigns missing resources if

-   If you want to use the device in bus mastering mode, call pci_set_master()
-which enables the bus master bit in PCI_COMMAND register and also fixes
-the latency timer value if it's set to something bogus by the BIOS.
+3. Device Initialization Steps
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As noted in the introduction, most PCI drivers need the following steps
+for device initialization:
 
-   If you want to use the PCI Memory-Write-Invalidate transaction,
+	Enable the device
+	Request MMIO/IOP resources
+	Set the DMA mask size (for both coherent and streaming DMA)
+	Allocate and initialize shared control data (pci_allocate_coherent())
+	Access device configuration space (if needed)
+	Register IRQ handler (request_irq())
+	Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
+	Enable DMA/processing engines.
+
+The driver can access PCI config space registers at any time.
+(Well, almost. When running BIST, config space can go away...but
+that will just result in a PCI Bus Master Abort and config reads
+will return garbage).
+
+
+3.1 Enable the PCI device
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Before touching any device registers, the driver needs to enable
+the PCI device by calling pci_enable_device(). This will:
+	o wake up the device if it was in suspended state,
+	o allocate I/O and memory regions of the device (if BIOS did not),
+	o allocate an IRQ (if BIOS did not).
+
+NOTE: pci_enable_device() can fail! Check the return value.
+NOTE2: Also see pci_enable_device_bars() below. Drivers can
+    attempt to enable only a subset of BARs they need.
+
+[ OS BUG: we don't check resource allocations before enabling those
+  resources. The sequence would make more sense if we called
+  pci_request_resources() before calling pci_enable_device().
+  Currently, the device drivers can't detect the bug when when two
+  devices have been allocated the same range. This is not a common
+  problem and unlikely to get fixed soon.
+
+  This has been discussed before but not changed as of 2.6.19:
+	http://lkml.org/lkml/2006/3/2/194
+]
+
+pci_set_master() will enable DMA by setting the bus master bit
+in the PCI_COMMAND register. It also fixes the latency timer value if
+it's set to something bogus by the BIOS.
+
+If the PCI device can use the PCI Memory-Write-Invalidate transaction,
 call pci_set_mwi().  This enables the PCI_COMMAND bit for Mem-Wr-Inval
 and also ensures that the cache line size register is set correctly.
-Make sure to check the return value of pci_set_mwi(), not all architectures
-may support Memory-Write-Invalidate.
+Check the return value of pci_set_mwi() as not all architectures
+or chip-sets may support Memory-Write-Invalidate.
+
+
+3.2 Request MMIO/IOP resources
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Memory (MMIO), and I/O port addresses should NOT be read directly
+from the PCI device config space. Use the values in the pci_dev structure
+as the PCI "bus address" might have been remapped to a "host physical"
+address by the arch/chip-set specific kernel support.
 
-   If your driver decides to stop using the device (e.g., there was an
-error while setting it up or the driver module is being unloaded), it
-should call pci_disable_device() to deallocate any IRQ resources, disable
-PCI bus-mastering, etc.  You should not do anything with the device after
+See Documentation/IO-mapping.txt for how to access device registers
+or device memory.
+
+The device driver needs to call pci_request_region() to verify
+no other device is already using the same address resource.
+Conversely, drivers should call pci_release_region() AFTER
 calling pci_disable_device().
+The idea is to prevent two devices colliding on the same address range.
+
+[ See OS BUG comment above. Currently (2.6.19), The driver can only
+  determine MMIO and IO Port resource availability _after_ calling
+  pci_enable_device(). ]
+
+Generic flavors of pci_request_region() are request_mem_region()
+(for MMIO ranges) and request_region() (for IO Port ranges).
+Use these for address resources that are not described by "normal" PCI
+BARs.
+
+Also see pci_request_selected_regions() below.
+
+
+3.3 Set the DMA mask size
+~~~~~~~~~~~~~~~~~~~~~~~~~
+[ If anything below doesn't make sense, please refer to
+  Documentation/DMA-API.txt. This section is just a reminder that
+  drivers need to indicate DMA capabilities of the device and is not
+  an authoritative source for DMA interfaces. ]
+
+While all drivers should explicitly indicate the DMA capability
+(e.g. 32 or 64 bit) of the PCI bus master, devices with more than
+32-bit bus master capability for streaming data need the driver
+to "register" this capability by calling pci_set_dma_mask() with
+appropriate parameters.  In general this allows more efficient DMA
+on systems where System RAM exists above 4G _physical_ address.
+
+Drivers for all PCI-X and PCIe compliant devices must call
+pci_set_dma_mask() as they are 64-bit DMA devices.
+
+Similarly, drivers must also "register" this capability if the device
+can directly address "consistent memory" in System RAM above 4G physical
+address by calling pci_set_consistent_dma_mask().
+Again, this includes drivers for all PCI-X and PCIe compliant devices.
+Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are
+64-bit DMA capable for payload ("streaming") data but not control
+("consistent") data.
+
+
+3.4 Setup shared control data
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared)
+memory.  See Documentation/DMA-API.txt for a full description of
+the DMA APIs. This section is just a reminder that it needs to be done
+before enabling DMA on the device.
+
+
+3.5 Initialize device registers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Some drivers will need specific "capability" fields programmed
+or other "vendor specific" register initialized or reset.
+E.g. clearing pending interrupts.
+
+
+3.6 Register IRQ handler
+~~~~~~~~~~~~~~~~~~~~~~~~
+While calling request_irq() is the the last step described here,
+this is often just another intermediate step to initialize a device.
+This step can often be deferred until the device is opened for use.
+
+All interrupt handlers for IRQ lines should be registered with IRQF_SHARED
+and use the devid to map IRQs to devices (remember that all PCI IRQ lines
+can be shared).
+
+request_irq() will associate an interrupt handler and device handle
+with an interrupt number. Historically interrupt numbers represent
+IRQ lines which run from the PCI device to the Interrupt controller.
+With MSI and MSI-X (more below) the interrupt number is a CPU "vector".
+
+request_irq() also enables the interrupt. Make sure the device is
+quiesced and does not have any interrupts pending before registering
+the interrupt handler.
+
+MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts"
+which deliver interrupts to the CPU via a DMA write to a Local APIC.
+The fundamental difference between MSI and MSI-X is how multiple
+"vectors" get allocated. MSI requires contiguous blocks of vectors
+while MSI-X can allocate several individual ones.
+
+MSI capability can be enabled by calling pci_enable_msi() or
+pci_enable_msix() before calling request_irq(). This causes
+the PCI support to program CPU vector data into the PCI device
+capability registers.
+
+If your PCI device supports both, try to enable MSI-X first.
+Only one can be enabled at a time.  Many architectures, chip-sets,
+or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix
+will fail. This is important to note since many drivers have
+two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs.
+They choose which handler to register with request_irq() based on the
+return value from pci_enable_msi/msix().
+
+There are (at least) two really good reasons for using MSI:
+1) MSI is an exclusive interrupt vector by definition.
+   This means the interrupt handler doesn't have to verify
+   its device caused the interrupt.
+
+2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed
+   to be visible to the host CPU(s) when the MSI is delivered. This
+   is important for both data coherency and avoiding stale control data.
+   This guarantee allows the driver to omit MMIO reads to flush
+   the DMA stream.
+
+See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples
+of MSI/MSI-X usage.
+
+
+
+4. PCI device shutdown
+~~~~~~~~~~~~~~~~~~~~~~~
+
+When a PCI device driver is being unloaded, most of the following
+steps need to be performed:
+
+	Disable the device from generating IRQs
+	Release the IRQ (free_irq())
+	Stop all DMA activity
+	Release DMA buffers (both streaming and consistent)
+	Unregister from other subsystems (e.g. scsi or netdev)
+	Disable device from responding to MMIO/IO Port addresses
+	Release MMIO/IO Port resource(s)
+
+
+4.1 Stop IRQs on the device
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+How to do this is chip/device specific. If it's not done, it opens
+the possibility of a "screaming interrupt" if (and only if)
+the IRQ is shared with another device.
+
+When the shared IRQ handler is "unhooked", the remaining devices
+using the same IRQ line will still need the IRQ enabled. Thus if the
+"unhooked" device asserts IRQ line, the system will respond assuming
+it was one of the remaining devices asserted the IRQ line. Since none
+of the other devices will handle the IRQ, the system will "hang" until
+it decides the IRQ isn't going to get handled and masks the IRQ (100,000
+iterations later). Once the shared IRQ is masked, the remaining devices
+will stop functioning properly. Not a nice situation.
+
+This is another reason to use MSI or MSI-X if it's available.
+MSI and MSI-X are defined to be exclusive interrupts and thus
+are not susceptible to the "screaming interrupt" problem.
+
+
+4.2 Release the IRQ
+~~~~~~~~~~~~~~~~~~~
+Once the device is quiesced (no more IRQs), one can call free_irq().
+This function will return control once any pending IRQs are handled,
+"unhook" the drivers IRQ handler from that IRQ, and finally release
+the IRQ if no one else is using it.
+
+
+4.3 Stop all DMA activity
+~~~~~~~~~~~~~~~~~~~~~~~~~
+It's extremely important to stop all DMA operations BEFORE attempting
+to deallocate DMA control data. Failure to do so can result in memory
+corruption, hangs, and on some chip-sets a hard crash.
 
-4. How to access PCI config space
+Stopping DMA after stopping the IRQs can avoid races where the
+IRQ handler might restart DMA engines.
+
+While this step sounds obvious and trivial, several "mature" drivers
+didn't get this step right in the past.
+
+
+4.4 Release DMA buffers
+~~~~~~~~~~~~~~~~~~~~~~~
+Once DMA is stopped, clean up streaming DMA first.
+I.e. unmap data buffers and return buffers to "upstream"
+owners if there is one.
+
+Then clean up "consistent" buffers which contain the control data.
+
+See Documentation/DMA-API.txt for details on unmapping interfaces.
+
+
+4.5 Unregister from other subsystems
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Most low level PCI device drivers support some other subsystem
+like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your
+driver isn't losing resources from that other subsystem.
+If this happens, typically the symptom is an Oops (panic) when
+the subsystem attempts to call into a driver that has been unloaded.
+
+
+4.6 Disable Device from responding to MMIO/IO Port addresses
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+io_unmap() MMIO or IO Port resources and then call pci_disable_device().
+This is the symmetric opposite of pci_enable_device().
+Do not access device registers after calling pci_disable_device().
+
+
+4.7 Release MMIO/IO Port Resource(s)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Call pci_release_region() to mark the MMIO or IO Port range as available.
+Failure to do so usually results in the inability to reload the driver.

+
+
+
+10. pci_enable_device_bars() and Legacy I/O Port space
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Large servers may not be able to provide I/O port resources to all PCI
+devices. I/O Port space is only 64KB on Intel Architecture[1] and is
+likely also fragmented since the I/O base register of PCI-to-PCI
+bridge will usually be aligned to a 4KB boundary[2]. On such systems,
+pci_enable_device() and pci_request_region() will fail when
+attempting to enable I/O Port regions that don't have I/O Port
+resources assigned.
+
+Fortunately, many PCI devices which request I/O Port resources also
+provide access to the same registers via MMIO BARs. These devices can
+be handled without using I/O port space and the drivers typically
+offer a CONFIG_ option to only use MMIO regions
+(e.g. CONFIG_TULIP_MMIO). PCI devices typically provide I/O port
+interface for legacy OSes and will work when I/O port resources are not
+assigned. The "PCI Local Bus Specification Revision 3.0" discusses
+this on p.44, "IMPLEMENTATION NOTE".
+
+If your PCI device driver doesn't need I/O port resources assigned to
+I/O Port BARs, you should use pci_enable_device_bars() instead of
+pci_enable_device() in order not to enable I/O port regions for the
+corresponding devices. In addition, you should use
+pci_request_selected_regions() and pci_release_selected_regions()
+instead of pci_request_regions()/pci_release_regions() in order not to
+request/release I/O port regions for the corresponding devices.
+
+[1] Some systems support 64KB I/O port space per PCI segment.
+[2] Some PCI-to-PCI bridges support optional 1KB aligned I/O base.
+
+
+
+11. MMIO Space and "Write Posting"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Converting a driver from using I/O Port space to using MMIO space
+often requires some additional changes. Specifically, "write posting"
+needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2)
+already do this. I/O Port space guarantees write transactions reach the PCI
+device before the CPU can continue. Writes to MMIO space allow the CPU
+to continue before the transaction reaches the PCI device. HW weenies
+call this "Write Posting" because the write completion is "posted" to
+the CPU before the transaction has reached its destination.
+
+Thus, timing sensitive code should add readl() where the CPU is
+expected to wait before doing other work.  The classic "bit banging"
+sequence works fine for I/O Port space:
+
+       for (i = 8; --i; val >>= 1) {
+               outb(val & 1, ioport_reg);      /* write bit */
+               udelay(10);
+       }
+
+The same sequence for MMIO space should be:
+
+       for (i = 8; --i; val >>= 1) {
+               writeb(val & 1, mmio_reg);      /* write bit */
+               readb(safe_mmio_reg);           /* flush posted write */
+               udelay(10);
+       }
+
+It is important that "safe_mmio_reg" not have any side effects that
+interferes with the correct operation of the device.

+Another case to watch out for is when resetting a PCI device. Use PCI
+Configuration space reads to flush the writel(). This will gracefully
+handle the PCI master abort on all platforms if the PCI device is
+expected to not respond to a readl().  Most x86 platforms will allow
+MMIO reads to master abort (a.k.a. "Soft Fail") and return garbage
+(e.g. ~0). But many RISC platforms will crash (a.k.a."Hard Fail").

 In this example, device 0815 is accessed via subchannel 0 in subchannel set 0,
 device 4711 via subchannel 1 in subchannel set 0, and subchannel 2 is a non-I/O
 subchannel. Device 1234 is accessed via subchannel 0 in subchannel set 1.
 
+The subchannel named 'defunct' does not represent any real subchannel on the
+system; it is a pseudo subchannel where disconnnected ccw devices are moved to
+if they are displaced by another ccw device becoming operational on their
+former subchannel. The ccw devices will be moved again to a proper subchannel
+if they become operational again on that subchannel.
+
 You should address a ccw device via its bus id (e.g. 0.0.4711); the device can
 be found under bus/ccw/devices/.

+ASoC currently supports the three main Digital Audio Interfaces (DAI) found on
+SoC controllers and portable audio CODECS today, namely AC97, I2S and PCM.
+
+
+AC97
+====
+
+  AC97 is a five wire interface commonly found on many PC sound cards. It is
+now also popular in many portable devices. This DAI has a reset line and time
+multiplexes its data on its SDATA_OUT (playback) and SDATA_IN (capture) lines.
+The bit clock (BCLK) is always driven by the CODEC (usually 12.288MHz) and the
+frame (FRAME) (usually 48kHz) is always driven by the controller. Each AC97
+frame is 21uS long and is divided into 13 time slots.
+
+The AC97 specification can be found at :-
+http://www.intel.com/design/chipsets/audio/ac97_r23.pdf
+
+
+I2S
+===
+
+ I2S is a common 4 wire DAI used in HiFi, STB and portable devices. The Tx and
+Rx lines are used for audio transmision, whilst the bit clock (BCLK) and
+left/right clock (LRC) synchronise the link. I2S is flexible in that either the
+controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock
+usually varies depending on the sample rate and the master system clock
+(SYSCLK). LRCLK is the same as the sample rate. A few devices support separate
+ADC and DAC LRCLK's, this allows for similtanious capture and playback at
+different sample rates.
+
+I2S has several different operating modes:-
+
+ o I2S - MSB is transmitted on the falling edge of the first BCLK after LRC
+         transition.
+
+ o Left Justified - MSB is transmitted on transition of LRC.
+
+ o Right Justified - MSB is transmitted sample size BCLK's before LRC
+                     transition.
+
+PCM
+===
+
+PCM is another 4 wire interface, very similar to I2S, that can support a more
+flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used
+to synchronise the link whilst the Tx and Rx lines are used to transmit and
+receive the audio data. Bit clock usually varies depending on sample rate
+whilst sync runs at the sample rate. PCM also supports Time Division
+Multiplexing (TDM) in that several devices can use the bus similtaniuosly (This
+is sometimes referred to as network mode).
+
+Common PCM operating modes:-
+
+ o Mode A - MSB is transmitted on falling edge of first BCLK after FRAME/SYNC.
+
+ o Mode B - MSB is transmitted on rising edge of FRAME/SYNC.

+Audio Clocking
+==============
+
+This text describes the audio clocking terms in ASoC and digital audio in
+general. Note: Audio clocking can be complex !
+
+
+Master Clock
+------------
+
+Every audio subsystem is driven by a master clock (sometimes refered to as MCLK
+or SYSCLK). This audio master clock can be derived from a number of sources
+(e.g. crystal, PLL, CPU clock) and is responsible for producing the correct
+audio playback and capture sample rates.
+
+Some master clocks (e.g. PLL's and CPU based clocks) are configuarble in that
+their speed can be altered by software (depending on the system use and to save
+power). Other master clocks are fixed at at set frequency (i.e. crystals).
+
+
+DAI Clocks
+----------
+The Digital Audio Interface is usually driven by a Bit Clock (often referred to
+as BCLK). This clock is used to drive the digital audio data across the link
+between the codec and CPU.
+
+The DAI also has a frame clock to signal the start of each audio frame. This
+clock is sometimes referred to as LRC (left right clock) or FRAME. This clock
+runs at exactly the sample rate (LRC = Rate).
+
+Bit Clock can be generated as follows:-
+
+BCLK = MCLK / x
+
+ or
+
+BCLK = LRC * x
+
+ or
+
+BCLK = LRC * Channels * Word Size
+
+This relationship depends on the codec or SoC CPU in particular. In general
+it's best to configure BCLK to the lowest possible speed (depending on your
+rate, number of channels and wordsize) to save on power.
+
+It's also desireable to use the codec (if possible) to drive (or master) the
+audio clocks as it's usually gives more accurate sample rates than the CPU.

+ASoC Codec Driver
+=================
+
+The codec driver is generic and hardware independent code that configures the
+codec to provide audio capture and playback. It should contain no code that is
+specific to the target platform or machine. All platform and machine specific
+code should be added to the platform and machine drivers respectively.
+
+Each codec driver *must* provide the following features:-
+
+ 1) Codec DAI and PCM configuration
+ 2) Codec control IO - using I2C, 3 Wire(SPI) or both API's
+ 3) Mixers and audio controls
+ 4) Codec audio operations
+
+Optionally, codec drivers can also provide:-
+
+ 5) DAPM description.
+ 6) DAPM event handler.
+ 7) DAC Digital mute control.
+
+It's probably best to use this guide in conjuction with the existing codec
+driver code in sound/soc/codecs/
+
+ASoC Codec driver breakdown
+===========================
+
+1 - Codec DAI and PCM configuration
+-----------------------------------
+Each codec driver must have a struct snd_soc_codec_dai to define it's DAI and
+PCM's capablities and operations. This struct is exported so that it can be
+registered with the core by your machine driver.
+
+e.g.
+
+struct snd_soc_codec_dai wm8731_dai = {
+	.name = "WM8731",
+	/* playback capabilities */
+	.playback = {
+		.stream_name = "Playback",
+		.channels_min = 1,
+		.channels_max = 2,
+		.rates = WM8731_RATES,
+		.formats = WM8731_FORMATS,},
+	/* capture capabilities */
+	.capture = {
+		.stream_name = "Capture",
+		.channels_min = 1,
+		.channels_max = 2,
+		.rates = WM8731_RATES,
+		.formats = WM8731_FORMATS,},
+	/* pcm operations - see section 4 below */
+	.ops = {
+		.prepare = wm8731_pcm_prepare,
+		.hw_params = wm8731_hw_params,
+		.shutdown = wm8731_shutdown,
+	},
+	/* DAI operations - see DAI.txt */
+	.dai_ops = {
+		.digital_mute = wm8731_mute,
+		.set_sysclk = wm8731_set_dai_sysclk,
+		.set_fmt = wm8731_set_dai_fmt,
+	}
+};
+EXPORT_SYMBOL_GPL(wm8731_dai);
+
+
+2 - Codec control IO
+--------------------
+The codec can ususally be controlled via an I2C or SPI style interface (AC97
+combines control with data in the DAI). The codec drivers will have to provide
+functions to read and write the codec registers along with supplying a register
+cache:-
+
+	/* IO control data and register cache */
+    void *control_data; /* codec control (i2c/3wire) data */
+    void *reg_cache;
+
+Codec read/write should do any data formatting and call the hardware read write
+below to perform the IO. These functions are called by the core and alsa when
+performing DAPM or changing the mixer:-
+
+    unsigned int (*read)(struct snd_soc_codec *, unsigned int);
+    int (*write)(struct snd_soc_codec *, unsigned int, unsigned int);
+
+Codec hardware IO functions - usually points to either the I2C, SPI or AC97
+read/write:-
+
+	hw_write_t hw_write;
+	hw_read_t hw_read;
+
+
+3 - Mixers and audio controls
+-----------------------------
+All the codec mixers and audio controls can be defined using the convenience
+macros defined in soc.h.
+
+    #define SOC_SINGLE(xname, reg, shift, mask, invert)
+
+Defines a single control as follows:-
+
+  xname = Control name e.g. "Playback Volume"
+  reg = codec register
+  shift = control bit(s) offset in register
+  mask = control bit size(s) e.g. mask of 7 = 3 bits
+  invert = the control is inverted
+
+Other macros include:-
+
+    #define SOC_DOUBLE(xname, reg, shift_left, shift_right, mask, invert)
+
+A stereo control
+
+    #define SOC_DOUBLE_R(xname, reg_left, reg_right, shift, mask, invert)
+
+A stereo control spanning 2 registers
+
+    #define SOC_ENUM_SINGLE(xreg, xshift, xmask, xtexts)
+
+Defines an single enumerated control as follows:-
+
+   xreg = register
+   xshift = control bit(s) offset in register
+   xmask = control bit(s) size
+   xtexts = pointer to array of strings that describe each setting
+
+   #define SOC_ENUM_DOUBLE(xreg, xshift_l, xshift_r, xmask, xtexts)
+
+Defines a stereo enumerated control
+
+
+4 - Codec Audio Operations
+--------------------------
+The codec driver also supports the following alsa operations:-
+
+/* SoC audio ops */
+struct snd_soc_ops {
+	int (*startup)(struct snd_pcm_substream *);
+	void (*shutdown)(struct snd_pcm_substream *);
+	int (*hw_params)(struct snd_pcm_substream *, struct snd_pcm_hw_params *);
+	int (*hw_free)(struct snd_pcm_substream *);
+	int (*prepare)(struct snd_pcm_substream *);
+};
+
+Please refer to the alsa driver PCM documentation for details.
+http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
+
+
+5 - DAPM description.
+---------------------
+The Dynamic Audio Power Management description describes the codec's power
+components, their relationships and registers to the ASoC core. Please read
+dapm.txt for details of building the description.
+
+Please also see the examples in other codec drivers.
+
+
+6 - DAPM event handler
+----------------------
+This function is a callback that handles codec domain PM calls and system
+domain PM calls (e.g. suspend and resume). It's used to put the codec to sleep
+when not in use.
+
+Power states:-
+
+	SNDRV_CTL_POWER_D0: /* full On */
+	/* vref/mid, clk and osc on, active */
+
+	SNDRV_CTL_POWER_D1: /* partial On */
+	SNDRV_CTL_POWER_D2: /* partial On */
+
+	SNDRV_CTL_POWER_D3hot: /* Off, with power */
+	/* everything off except vref/vmid, inactive */
+
+	SNDRV_CTL_POWER_D3cold: /* Everything Off, without power */
+
+
+7 - Codec DAC digital mute control.
+------------------------------------
+Most codecs have a digital mute before the DAC's that can be used to minimise
+any system noise.  The mute stops any digital data from entering the DAC.
+
+A callback can be created that is called by the core for each codec DAI when the
+mute is applied or freed.
+
+i.e.
+
+static int wm8974_mute(struct snd_soc_codec *codec,
+	struct snd_soc_codec_dai *dai, int mute)
+{
+	u16 mute_reg = wm8974_read_reg_cache(codec, WM8974_DAC) & 0xffbf;
+	if(mute)
+		wm8974_write(codec, WM8974_DAC, mute_reg | 0x40);
+	else
+		wm8974_write(codec, WM8974_DAC, mute_reg);
+	return 0;
+}

+Dynamic Audio Power Management for Portable Devices
+===================================================
+
+1. Description
+==============
+
+Dynamic Audio Power Management (DAPM) is designed to allow portable Linux devices
+to use the minimum amount of power within the audio subsystem at all times. It
+is independent of other kernel PM and as such, can easily co-exist with the
+other PM systems.
+
+DAPM is also completely transparent to all user space applications as all power
+switching is done within the ASoC core. No code changes or recompiling are
+required for user space applications. DAPM makes power switching descisions based
+upon any audio stream (capture/playback) activity and audio mixer settings
+within the device.
+
+DAPM spans the whole machine. It covers power control within the entire audio
+subsystem, this includes internal codec power blocks and machine level power
+systems.
+
+There are 4 power domains within DAPM
+
+   1. Codec domain - VREF, VMID (core codec and audio power)
+      Usually controlled at codec probe/remove and suspend/resume, although
+      can be set at stream time if power is not needed for sidetone, etc.
+
+   2. Platform/Machine domain - physically connected inputs and outputs
+      Is platform/machine and user action specific, is configured by the
+      machine driver and responds to asynchronous events e.g when HP
+      are inserted
+
+   3. Path domain - audio susbsystem signal paths
+      Automatically set when mixer and mux settings are changed by the user.
+      e.g. alsamixer, amixer.
+
+   4. Stream domain - DAC's and ADC's.
+      Enabled and disabled when stream playback/capture is started and
+      stopped respectively. e.g. aplay, arecord.
+
+All DAPM power switching descisons are made automatically by consulting an audio
+routing map of the whole machine. This map is specific to each machine and
+consists of the interconnections between every audio component (including
+internal codec components). All audio components that effect power are called
+widgets hereafter.
+
+
+2. DAPM Widgets
+===============
+
+Audio DAPM widgets fall into a number of types:-
+
+ o Mixer      - Mixes several analog signals into a single analog signal.
+ o Mux        - An analog switch that outputs only 1 of it's inputs.
+ o PGA        - A programmable gain amplifier or attenuation widget.
+ o ADC        - Analog to Digital Converter
+ o DAC        - Digital to Analog Converter
+ o Switch     - An analog switch
+ o Input      - A codec input pin
+ o Output     - A codec output pin
+ o Headphone  - Headphone (and optional Jack)
+ o Mic        - Mic (and optional Jack)
+ o Line       - Line Input/Output (and optional Jack)
+ o Speaker    - Speaker
+ o Pre        - Special PRE widget (exec before all others)
+ o Post       - Special POST widget (exec after all others)
+
+(Widgets are defined in include/sound/soc-dapm.h)
+
+Widgets are usually added in the codec driver and the machine driver. There are
+convience macros defined in soc-dapm.h that can be used to quickly build a
+list of widgets of the codecs and machines DAPM widgets.
+
+Most widgets have a name, register, shift and invert. Some widgets have extra
+parameters for stream name and kcontrols.
+
+
+2.1 Stream Domain Widgets
+-------------------------
+
+Stream Widgets relate to the stream power domain and only consist of ADC's
+(analog to digital converters) and DAC's (digital to analog converters).
+
+Stream widgets have the following format:-
+
+SND_SOC_DAPM_DAC(name, stream name, reg, shift, invert),
+
+NOTE: the stream name must match the corresponding stream name in your codecs
+snd_soc_codec_dai.
+
+e.g. stream widgets for HiFi playback and capture
+
+SND_SOC_DAPM_DAC("HiFi DAC", "HiFi Playback", REG, 3, 1),
+SND_SOC_DAPM_ADC("HiFi ADC", "HiFi Capture", REG, 2, 1),
+
+
+2.2 Path Domain Widgets
+-----------------------
+
+Path domain widgets have a ability to control or effect the audio signal or
+audio paths within the audio subsystem. They have the following form:-
+
+SND_SOC_DAPM_PGA(name, reg, shift, invert, controls, num_controls)
+
+Any widget kcontrols can be set using the controls and num_controls members.
+
+e.g. Mixer widget (the kcontrols are declared first)
+
+/* Output Mixer */
+static const snd_kcontrol_new_t wm8731_output_mixer_controls[] = {
+SOC_DAPM_SINGLE("Line Bypass Switch", WM8731_APANA, 3, 1, 0),
+SOC_DAPM_SINGLE("Mic Sidetone Switch", WM8731_APANA, 5, 1, 0),
+SOC_DAPM_SINGLE("HiFi Playback Switch", WM8731_APANA, 4, 1, 0),
+};
+
+SND_SOC_DAPM_MIXER("Output Mixer", WM8731_PWR, 4, 1, wm8731_output_mixer_controls,
+	ARRAY_SIZE(wm8731_output_mixer_controls)),
+
+
+2.3 Platform/Machine domain Widgets
+-----------------------------------
+
+Machine widgets are different from codec widgets in that they don't have a
+codec register bit associated with them. A machine widget is assigned to each
+machine audio component (non codec) that can be independently powered. e.g.
+
+ o Speaker Amp
+ o Microphone Bias
+ o Jack connectors
+
+A machine widget can have an optional call back.
+
+e.g. Jack connector widget for an external Mic that enables Mic Bias
+when the Mic is inserted:-
+
+static int spitz_mic_bias(struct snd_soc_dapm_widget* w, int event)
+{
+	if(SND_SOC_DAPM_EVENT_ON(event))
+		set_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
+	else
+		reset_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
+
+	return 0;
+}
+
+SND_SOC_DAPM_MIC("Mic Jack", spitz_mic_bias),
+
+
+2.4 Codec Domain
+----------------
+
+The Codec power domain has no widgets and is handled by the codecs DAPM event
+handler. This handler is called when the codec powerstate is changed wrt to any
+stream event or by kernel PM events.
+
+
+2.5 Virtual Widgets
+-------------------
+
+Sometimes widgets exist in the codec or machine audio map that don't have any
+corresponding register bit for power control. In this case it's necessary to
+create a virtual widget - a widget with no control bits e.g.
+
+SND_SOC_DAPM_MIXER("AC97 Mixer", SND_SOC_DAPM_NOPM, 0, 0, NULL, 0),
+
+This can be used to merge to signal paths together in software.
+
+After all the widgets have been defined, they can then be added to the DAPM
+subsystem individually with a call to snd_soc_dapm_new_control().
+
+
+3. Codec Widget Interconnections
+================================
+
+Widgets are connected to each other within the codec and machine by audio
+paths (called interconnections). Each interconnection must be defined in order
+to create a map of all audio paths between widgets.
+This is easiest with a diagram of the codec (and schematic of the machine audio
+system), as it requires joining widgets together via their audio signal paths.
+
+i.e. from the WM8731 codec's output mixer (wm8731.c)
+
+The WM8731 output mixer has 3 inputs (sources)
+
+ 1. Line Bypass Input
+ 2. DAC (HiFi playback)
+ 3. Mic Sidetone Input
+
+Each input in this example has a kcontrol associated with it (defined in example
+above) and is connected to the output mixer via it's kcontrol name. We can now
+connect the destination widget (wrt audio signal) with it's source widgets.
+
+	/* output mixer */
+	{"Output Mixer", "Line Bypass Switch", "Line Input"},
+	{"Output Mixer", "HiFi Playback Switch", "DAC"},
+	{"Output Mixer", "Mic Sidetone Switch", "Mic Bias"},
+
+So we have :-
+
+	Destination Widget  <=== Path Name <=== Source Widget
+
+Or:-
+
+	Sink, Path, Source
+
+Or :-
+
+	"Output Mixer" is connected to the "DAC" via the "HiFi Playback Switch".
+
+When there is no path name connecting widgets (e.g. a direct connection) we
+pass NULL for the path name.
+
+Interconnections are created with a call to:-
+
+snd_soc_dapm_connect_input(codec, sink, path, source);
+
+Finally, snd_soc_dapm_new_widgets(codec) must be called after all widgets and
+interconnections have been registered with the core. This causes the core to
+scan the codec and machine so that the internal DAPM state matches the
+physical state of the machine.
+
+
+3.1 Machine Widget Interconnections
+-----------------------------------
+Machine widget interconnections are created in the same way as codec ones and
+directly connect the codec pins to machine level widgets.
+
+e.g. connects the speaker out codec pins to the internal speaker.
+
+	/* ext speaker connected to codec pins LOUT2, ROUT2  */
+	{"Ext Spk", NULL , "ROUT2"},
+	{"Ext Spk", NULL , "LOUT2"},
+
+This allows the DAPM to power on and off pins that are connected (and in use)
+and pins that are NC respectively.
+
+
+4 Endpoint Widgets
+===================
+An endpoint is a start or end point (widget) of an audio signal within the
+machine and includes the codec. e.g.
+
+ o Headphone Jack
+ o Internal Speaker
+ o Internal Mic
+ o Mic Jack
+ o Codec Pins
+
+When a codec pin is NC it can be marked as not used with a call to
+
+snd_soc_dapm_set_endpoint(codec, "Widget Name", 0);
+
+The last argument is 0 for inactive and 1 for active. This way the pin and its
+input widget will never be powered up and consume power.
+
+This also applies to machine widgets. e.g. if a headphone is connected to a
+jack then the jack can be marked active. If the headphone is removed, then
+the headphone jack can be marked inactive.
+
+
+5 DAPM Widget Events
+====================
+
+Some widgets can register their interest with the DAPM core in PM events.
+e.g. A Speaker with an amplifier registers a widget so the amplifier can be
+powered only when the spk is in use.
+
+/* turn speaker amplifier on/off depending on use */
+static int corgi_amp_event(struct snd_soc_dapm_widget *w, int event)
+{
+	if (SND_SOC_DAPM_EVENT_ON(event))
+		set_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
+	else
+		reset_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
+
+	return 0;
+}
+
+/* corgi machine dapm widgets */
+static const struct snd_soc_dapm_widget wm8731_dapm_widgets =
+	SND_SOC_DAPM_SPK("Ext Spk", corgi_amp_event);
+
+Please see soc-dapm.h for all other widgets that support events.
+
+
+5.1 Event types
+---------------
+
+The following event types are supported by event widgets.
+
+/* dapm event types */
+#define SND_SOC_DAPM_PRE_PMU	0x1 	/* before widget power up */
+#define SND_SOC_DAPM_POST_PMU	0x2		/* after widget power up */
+#define SND_SOC_DAPM_PRE_PMD	0x4 	/* before widget power down */
+#define SND_SOC_DAPM_POST_PMD	0x8		/* after widget power down */
+#define SND_SOC_DAPM_PRE_REG	0x10	/* before audio path setup */
+#define SND_SOC_DAPM_POST_REG	0x20	/* after audio path setup */

+ASoC Machine Driver
+===================
+
+The ASoC machine (or board) driver is the code that glues together the platform
+and codec drivers.
+
+The machine driver can contain codec and platform specific code. It registers
+the audio subsystem with the kernel as a platform device and is represented by
+the following struct:-
+
+/* SoC machine */
+struct snd_soc_machine {
+	char *name;
+
+	int (*probe)(struct platform_device *pdev);
+	int (*remove)(struct platform_device *pdev);
+
+	/* the pre and post PM functions are used to do any PM work before and
+	 * after the codec and DAI's do any PM work. */
+	int (*suspend_pre)(struct platform_device *pdev, pm_message_t state);
+	int (*suspend_post)(struct platform_device *pdev, pm_message_t state);
+	int (*resume_pre)(struct platform_device *pdev);
+	int (*resume_post)(struct platform_device *pdev);
+
+	/* machine stream operations */
+	struct snd_soc_ops *ops;
+
+	/* CPU <--> Codec DAI links  */
+	struct snd_soc_dai_link *dai_link;
+	int num_links;
+};
+
+probe()/remove()
+----------------
+probe/remove are optional. Do any machine specific probe here.
+
+
+suspend()/resume()
+------------------
+The machine driver has pre and post versions of suspend and resume to take care
+of any machine audio tasks that have to be done before or after the codec, DAI's
+and DMA is suspended and resumed. Optional.
+
+
+Machine operations
+------------------
+The machine specific audio operations can be set here. Again this is optional.
+
+
+Machine DAI Configuration
+-------------------------
+The machine DAI configuration glues all the codec and CPU DAI's together. It can
+also be used to set up the DAI system clock and for any machine related DAI
+initialisation e.g. the machine audio map can be connected to the codec audio
+map, unconnnected codec pins can be set as such. Please see corgi.c, spitz.c
+for examples.
+
+struct snd_soc_dai_link is used to set up each DAI in your machine. e.g.
+
+/* corgi digital audio interface glue - connects codec <--> CPU */
+static struct snd_soc_dai_link corgi_dai = {
+	.name = "WM8731",
+	.stream_name = "WM8731",
+	.cpu_dai = &pxa_i2s_dai,
+	.codec_dai = &wm8731_dai,
+	.init = corgi_wm8731_init,
+	.ops = &corgi_ops,
+};
+
+struct snd_soc_machine then sets up the machine with it's DAI's. e.g.
+
+/* corgi audio machine driver */
+static struct snd_soc_machine snd_soc_machine_corgi = {
+	.name = "Corgi",
+	.dai_link = &corgi_dai,
+	.num_links = 1,
+};
+
+
+Machine Audio Subsystem
+-----------------------
+
+The machine soc device glues the platform, machine and codec driver together.
+Private data can also be set here. e.g.
+
+/* corgi audio private data */
+static struct wm8731_setup_data corgi_wm8731_setup = {
+	.i2c_address = 0x1b,
+};
+
+/* corgi audio subsystem */
+static struct snd_soc_device corgi_snd_devdata = {
+	.machine = &snd_soc_machine_corgi,
+	.platform = &pxa2xx_soc_platform,
+	.codec_dev = &soc_codec_dev_wm8731,
+	.codec_data = &corgi_wm8731_setup,
+};
+
+
+Machine Power Map
+-----------------
+
+The machine driver can optionally extend the codec power map and to become an
+audio power map of the audio subsystem. This allows for automatic power up/down
+of speaker/HP amplifiers, etc. Codec pins can be connected to the machines jack
+sockets in the machine init function. See soc/pxa/spitz.c and dapm.txt for
+details.
+
+
+Machine Controls
+----------------
+
+Machine specific audio mixer controls can be added in the dai init function.

+ALSA SoC Layer
+==============
+
+The overall project goal of the ALSA System on Chip (ASoC) layer is to provide
+better ALSA support for embedded system on chip procesors (e.g. pxa2xx, au1x00,
+iMX, etc) and portable audio codecs. Currently there is some support in the
+kernel for SoC audio, however it has some limitations:-
+
+  * Currently, codec drivers are often tightly coupled to the underlying SoC
+    cpu. This is not ideal and leads to code duplication i.e. Linux now has 4
+    different wm8731 drivers for 4 different SoC platforms.
+
+  * There is no standard method to signal user initiated audio events.
+    e.g. Headphone/Mic insertion, Headphone/Mic detection after an insertion
+    event. These are quite common events on portable devices and ofter require
+    machine specific code to re route audio, enable amps etc after such an event.
+
+  * Current drivers tend to power up the entire codec when playing
+    (or recording) audio. This is fine for a PC, but tends to waste a lot of
+    power on portable devices. There is also no support for saving power via
+    changing codec oversampling rates, bias currents, etc.
+
+
+ASoC Design
+===========
+
+The ASoC layer is designed to address these issues and provide the following
+features :-
+
+  * Codec independence. Allows reuse of codec drivers on other platforms
+    and machines.
+
+  * Easy I2S/PCM audio interface setup between codec and SoC. Each SoC interface
+    and codec registers it's audio interface capabilities with the core and are
+    subsequently matched and configured when the application hw params are known.
+
+  * Dynamic Audio Power Management (DAPM). DAPM automatically sets the codec to
+    it's minimum power state at all times. This includes powering up/down
+    internal power blocks depending on the internal codec audio routing and any
+    active streams.
+
+  * Pop and click reduction. Pops and clicks can be reduced by powering the
+    codec up/down in the correct sequence (including using digital mute). ASoC
+    signals the codec when to change power states.
+
+  * Machine specific controls: Allow machines to add controls to the sound card
+    e.g. volume control for speaker amp.
+
+To achieve all this, ASoC basically splits an embedded audio system into 3
+components :-
+
+  * Codec driver: The codec driver is platform independent and contains audio
+    controls, audio interface capabilities, codec dapm definition and codec IO
+    functions.
+
+  * Platform driver: The platform driver contains the audio dma engine and audio
+    interface drivers (e.g. I2S, AC97, PCM) for that platform.
+
+  * Machine driver: The machine driver handles any machine specific controls and
+    audio events. i.e. turing on an amp at start of playback.

+ASoC Platform Driver
+====================
+
+An ASoC platform driver can be divided into audio DMA and SoC DAI configuration
+and control. The platform drivers only target the SoC CPU and must have no board
+specific code.
+
+Audio DMA
+=========
+
+The platform DMA driver optionally supports the following alsa operations:-
+
+/* SoC audio ops */
+struct snd_soc_ops {
+	int (*startup)(struct snd_pcm_substream *);
+	void (*shutdown)(struct snd_pcm_substream *);
+	int (*hw_params)(struct snd_pcm_substream *, struct snd_pcm_hw_params *);
+	int (*hw_free)(struct snd_pcm_substream *);
+	int (*prepare)(struct snd_pcm_substream *);
+	int (*trigger)(struct snd_pcm_substream *, int);
+};
+
+The platform driver exports it's DMA functionailty via struct snd_soc_platform:-
+
+struct snd_soc_platform {
+	char *name;
+
+	int (*probe)(struct platform_device *pdev);
+	int (*remove)(struct platform_device *pdev);
+	int (*suspend)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
+	int (*resume)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
+
+	/* pcm creation and destruction */
+	int (*pcm_new)(struct snd_card *, struct snd_soc_codec_dai *, struct snd_pcm *);
+	void (*pcm_free)(struct snd_pcm *);
+
+	/* platform stream ops */
+	struct snd_pcm_ops *pcm_ops;
+};
+
+Please refer to the alsa driver documentation for details of audio DMA.
+http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
+
+An example DMA driver is soc/pxa/pxa2xx-pcm.c
+
+
+SoC DAI Drivers
+===============
+
+Each SoC DAI driver must provide the following features:-
+
+ 1) Digital audio interface (DAI) description
+ 2) Digital audio interface configuration
+ 3) PCM's description
+ 4) Sysclk configuration
+ 5) Suspend and resume (optional)
+
+Please see codec.txt for a description of items 1 - 4.

+Audio Pops and Clicks
+=====================
+
+Pops and clicks are unwanted audio artifacts caused by the powering up and down
+of components within the audio subsystem. This is noticable on PC's when an
+audio module is either loaded or unloaded (at module load time the sound card is
+powered up and causes a popping noise on the speakers).
+
+Pops and clicks can be more frequent on portable systems with DAPM. This is
+because the components within the subsystem are being dynamically powered
+depending on the audio usage and this can subsequently cause a small pop or
+click every time a component power state is changed.
+
+
+Minimising Playback Pops and Clicks
+===================================
+
+Playback pops in portable audio subsystems cannot be completely eliminated atm,
+however future audio codec hardware will have better pop and click supression.
+Pops can be reduced within playback by powering the audio components in a
+specific order. This order is different for startup and shutdown and follows
+some basic rules:-
+
+ Startup Order :- DAC --> Mixers --> Output PGA --> Digital Unmute
+
+ Shutdown Order :- Digital Mute --> Output PGA --> Mixers --> DAC
+
+This assumes that the codec PCM output path from the DAC is via a mixer and then
+a PGA (programmable gain amplifier) before being output to the speakers.
+
+
+Minimising Capture Pops and Clicks
+==================================
+
+Capture artifacts are somewhat easier to get rid as we can delay activating the
+ADC until all the pops have occured. This follows similar power rules to
+playback in that components are powered in a sequence depending upon stream
+startup or shutdown.
+
+ Startup Order - Input PGA --> Mixers --> ADC
+
+ Shutdown Order - ADC --> Mixers --> Input PGA
+
+
+Zipper Noise
+============
+An unwanted zipper noise can occur within the audio playback or capture stream
+when a volume control is changed near its maximum gain value. The zipper noise
+is heard when the gain increase or decrease changes the mean audio signal
+amplitude too quickly. It can be minimised by enabling the zero cross setting
+for each volume control. The ZC forces the gain change to occur when the signal
+crosses the zero amplitude line.

+Driver Access
+
+Line discipline methods can call the following methods of the underlying
+hardware driver through the function pointers within the tty->driver
+structure:
+
+write()			Write a block of characters to the tty device.
+			Returns the number of characters accepted.
+
+put_char()		Queues a character for writing to the tty device.
+			If there is no room in the queue, the character is
+			ignored.
+
+flush_chars()		(Optional) If defined, must be called after
+			queueing characters with put_char() in order to
+			start transmission.
+
+write_room()		Returns the numbers of characters the tty driver
+			will accept for queueing to be written.
+
+ioctl()			Invoke device specific ioctl.
+			Expects data pointers to refer to userspace.
+			Returns ENOIOCTLCMD for unrecognized ioctl numbers.
+
+set_termios()		Notify the tty driver that the device's termios
+			settings have changed. New settings are in
+			tty->termios. Previous settings should be passed in
+			the "old" argument.
+
+throttle()		Notify the tty driver that input buffers for the
+			line discipline are close to full, and it should
+			somehow signal that no more characters should be
+			sent to the tty.
+
+unthrottle()		Notify the tty driver that characters can now be
+			sent to the tty without fear of overrunning the
+			input buffers of the line disciplines.
+
+stop()			Ask the tty driver to stop outputting characters
+			to the tty device.
+
+start()			Ask the tty driver to resume sending characters
+			to the tty device.
+
+hangup()		Ask the tty driver to hang up the tty device.
+
+break_ctl()		(Optional) Ask the tty driver to turn on or off
+			BREAK status on the RS-232 port.  If state is -1,
+			then the BREAK status should be turned on; if
+			state is 0, then BREAK should be turned off.
+			If this routine is not implemented, use ioctls
+			TIOCSBRK / TIOCCBRK instead.
+
+wait_until_sent()	Waits until the device has written out all of the
+			characters in its transmitter FIFO.
+
+send_xchar()		Send a high-priority XON/XOFF character to the device.
+
+
+Flags
+
+Line discipline methods have access to tty->flags field containing the
+following interesting flags:
+
+TTY_THROTTLED		Driver input is throttled. The ldisc should call
+			tty->driver->unthrottle() in order to resume
+			reception when it is ready to process more data.
+
+TTY_DO_WRITE_WAKEUP	If set, causes the driver to call the ldisc's
+			write_wakeup() method in order to resume
+			transmission when it can accept more data
+			to transmit.
+
+TTY_IO_ERROR		If set, causes all subsequent userspace read/write
+			calls on the tty to fail, returning -EIO.
+
+TTY_OTHER_CLOSED	Device is a pty and the other side has closed.
+
+TTY_NO_WRITE_SPLIT	Prevent driver from splitting up writes into
+			smaller chunks.

 * Raw binary format and API
 
-TBD
+The overall architecture of the API is about the same as the one above,
+only the events are delivered in binary format. Each event is sent in
+the following structure (its name is made up, so that we can refer to it):
+
+struct usbmon_packet {
+	u64 id;			/*  0: URB ID - from submission to callback */
+	unsigned char type;	/*  8: Same as text; extensible. */
+	unsigned char xfer_type; /*    ISO (0), Intr, Control, Bulk (3) */
+	unsigned char epnum;	/*     Endpoint number and transfer direction */
+	unsigned char devnum;	/*     Device address */

+	unsigned int length;	/* 32: Length of data (submitted or actual) */
+	unsigned int len_cap;	/* 36: Delivered length */
+	unsigned char setup[8];	/* 40: Only for Control 'S' */
+};				/* 48 bytes total */
+
+These events can be received from a character device by reading with read(2),
+with an ioctl(2), or by accessing the buffer with mmap.
+
+The character device is usually called /dev/usbmonN, where N is the USB bus
+number. Number zero (/dev/usbmon0) is special and means "all buses".
+However, this feature is not implemented yet. Note that specific naming
+policy is set by your Linux distribution.
+
+If you create /dev/usbmon0 by hand, make sure that it is owned by root
+and has mode 0600. Otherwise, unpriviledged users will be able to snoop
+keyboard traffic.
+
+The following ioctl calls are available, with MON_IOC_MAGIC 0x92:
+
+ MON_IOCQ_URB_LEN, defined as _IO(MON_IOC_MAGIC, 1)
+
+This call returns the length of data in the next event. Note that majority of
+events contain no data, so if this call returns zero, it does not mean that
+no events are available.
+
+ MON_IOCG_STATS, defined as _IOR(MON_IOC_MAGIC, 3, struct mon_bin_stats)
+
+The argument is a pointer to the following structure:
+
+struct mon_bin_stats {
+	u32 queued;
+	u32 dropped;
+};
+
+The member "queued" refers to the number of events currently queued in the
+buffer (and not to the number of events processed since the last reset).
+
+The member "dropped" is the number of events lost since the last call
+to MON_IOCG_STATS.
+
+ MON_IOCT_RING_SIZE, defined as _IO(MON_IOC_MAGIC, 4)
+
+This call sets the buffer size. The argument is the size in bytes.
+The size may be rounded down to the next chunk (or page). If the requested
+size is out of [unspecified] bounds for this kernel, the call fails with
+-EINVAL.
+
+ MON_IOCQ_RING_SIZE, defined as _IO(MON_IOC_MAGIC, 5)
+
+This call returns the current size of the buffer in bytes.
+
+ MON_IOCX_GET, defined as _IOW(MON_IOC_MAGIC, 6, struct mon_get_arg)
+
+This call waits for events to arrive if none were in the kernel buffer,
+then returns the first event. Its argument is a pointer to the following
+structure:
+
+struct mon_get_arg {
+	struct usbmon_packet *hdr;
+	void *data;
+	size_t alloc;		/* Length of data (can be zero) */
+};
+
+Before the call, hdr, data, and alloc should be filled. Upon return, the area
+pointed by hdr contains the next event structure, and the data buffer contains
+the data, if any. The event is removed from the kernel buffer.
+
+ MON_IOCX_MFETCH, defined as _IOWR(MON_IOC_MAGIC, 7, struct mon_mfetch_arg)
+
+This ioctl is primarily used when the application accesses the buffer
+with mmap(2). Its argument is a pointer to the following structure:
+
+struct mon_mfetch_arg {
+	uint32_t *offvec;	/* Vector of events fetched */
+	uint32_t nfetch;	/* Number of events to fetch (out: fetched) */
+	uint32_t nflush;	/* Number of events to flush */
+};
+
+The ioctl operates in 3 stages.
+
+First, it removes and discards up to nflush events from the kernel buffer.
+The actual number of events discarded is returned in nflush.
+
+Second, it waits for an event to be present in the buffer, unless the pseudo-
+device is open with O_NONBLOCK.
+
+Third, it extracts up to nfetch offsets into the mmap buffer, and stores
+them into the offvec. The actual number of event offsets is stored into
+the nfetch.
+
+ MON_IOCH_MFLUSH, defined as _IO(MON_IOC_MAGIC, 8)
+
+This call removes a number of events from the kernel buffer. Its argument
+is the number of events to remove. If the buffer contains fewer events
+than requested, all events present are removed, and no error is reported.
+This works when no events are available too.
+
+ FIONBIO
+
+The ioctl FIONBIO may be implemented in the future, if there's a need.
+
+In addition to ioctl(2) and read(2), the special file of binary API can
+be polled with select(2) and poll(2). But lseek(2) does not work.
+
+* Memory-mapped access of the kernel buffer for the binary API
+
+The basic idea is simple:
+
+To prepare, map the buffer by getting the current size, then using mmap(2).
+Then, execute a loop similar to the one written in pseudo-code below:
+
+   struct mon_mfetch_arg fetch;
+   struct usbmon_packet *hdr;
+   int nflush = 0;
+   for (;;) {
+      fetch.offvec = vec; // Has N 32-bit words
+      fetch.nfetch = N;   // Or less than N
+      fetch.nflush = nflush;
+      ioctl(fd, MON_IOCX_MFETCH, &fetch);   // Process errors, too
+      nflush = fetch.nfetch;       // This many packets to flush when done
+      for (i = 0; i < nflush; i++) {
+         hdr = (struct ubsmon_packet *) &mmap_area[vec[i]];
+         if (hdr->type == '@')     // Filler packet
+            continue;
+         caddr_t data = &mmap_area[vec[i]] + 64;
+         process_packet(hdr, data);
+      }
+   }
+
+Thus, the main idea is to execute only one ioctl per N events.
+
+Although the buffer is circular, the returned headers and data do not cross
+the end of the buffer, so the above pseudo-code does not need any gathering.

+"cafe_ccic" is a driver for the Marvell 88ALP01 "cafe" CMOS camera
+controller.  This is the controller found in first-generation OLPC systems,
+and this driver was written with support from the OLPC project.
+
+Current status: the core driver works.  It can generate data in YUV422,
+RGB565, and RGB444 formats.  (Anybody looking at the code will see RGB32 as
+well, but that is a debugging aid which will be removed shortly).  VGA and
+QVGA modes work; CIF is there but the colors remain funky.  Only the OV7670
+sensor is known to work with this controller at this time.
+
+To try it out: either of these commands will work:
+
+     mplayer tv:// -tv driver=v4l2:width=640:height=480 -nosound
+     mplayer tv:// -tv driver=v4l2:width=640:height=480:outfmt=bgr16 -nosound
+
+The "xawtv" utility also works; gqcam does not, for unknown reasons.
+
+There are a few load-time options, most of which can be changed after
+loading via sysfs as well:
+
+ - alloc_bufs_at_load:  Normally, the driver will not allocate any DMA
+   buffers until the time comes to transfer data.  If this option is set,
+   then worst-case-sized buffers will be allocated at module load time.
+   This option nails down the memory for the life of the module, but
+   perhaps decreases the chances of an allocation failure later on.
+
+ - dma_buf_size: The size of DMA buffers to allocate.  Note that this
+   option is only consulted for load-time allocation; when buffers are
+   allocated at run time, they will be sized appropriately for the current
+   camera settings.
+
+ - n_dma_bufs: The controller can cycle through either two or three DMA
+   buffers.  Normally, the driver tries to use three buffers; on faster
+   systems, however, it will work well with only two.
+
+ - min_buffers: The minimum number of streaming I/O buffers that the driver
+   will consent to work with.  Default is one, but, on slower systems,
+   better behavior with mplayer can be achieved by setting to a higher
+   value (like six).
+
+ - max_buffers: The maximum number of streaming I/O buffers; default is
+   ten.  That number was carefully picked out of a hat and should not be
+   assumed to actually mean much of anything.
+
+ - flip: If this boolean parameter is set, the sensor will be instructed to
+   invert the video image.  Whether it makes sense is determined by how
+   your particular camera is mounted.
+
+Work is ongoing with this driver, stay tuned.

-Driver for Trust Computer Products Framegrabber, version 0.6.1
------- --- ----- -------- -------- ------------  ------- - - -
-
-- ZORAN ------------------------------------------------------
- Author: Pauline Middelink <middelin@polyware.nl>
-   Date: 18 September 1999
-Version: 0.6.1
-
-- Description ------------------------------------------------
-
-Video4Linux compatible driver for an unknown brand framegrabber
-(Sold in the Netherlands by TRUST Computer Products) and various
-other zoran zr36120 based framegrabbers.
-
-The card contains a ZR36120 Multimedia PCI Interface and a Philips
-SAA7110 Onechip Frontend videodecoder. There is also an DSP of
-which I have forgotten the number, since i will never get that thing
-to work without specs from the vendor itself.
-
-The SAA711x are capable of processing 6 different video inputs,
-CVBS1..6 and Y1+C1, Y2+C2, Y3+C3. All in 50/60Hz, NTSC, PAL or
-SECAM and delivering a YUV datastream.  On my card the input
-'CVBS-0' corresponds to channel CVBS2 and 'S-Video' to Y2+C2.
-
-I have some reports of other cards working with the mentioned
-chip sets. For a list of other working cards please have a look
-at the cards named in the tvcards struct in the beginning of
-zr36120.c
-
-After some testing, I discovered that the carddesigner messed up
-on the I2C interface. The Zoran chip includes 2 lines SDA and SCL
-which (s)he connected reversely. So we have to clock on the SDA
-and r/w data on the SCL pin. Life is fun... Each cardtype now has
-a bit which signifies if you have a card with the same deficiency.
-
-Oh, for the completeness of this story I must mention that my
-card delivers the VSYNC pulse of the SAA chip to GIRQ1, not
-GIRQ0 as some other cards have. This is also incorporated in
-the driver be clearing/setting the 'useirq1' bit in the tvcard
-description.
-
-Another problems of continuous capturing data with a Zoran chip
-is something nasty inside the chip. It effectively halves the
-fps we ought to get... Here is the scenario: capturing frames
-to memory is done in the so-called snapshot mode. In this mode
-the Zoran stops after capturing a frame worth of data and wait
-till the application set GRAB bit to indicate readiness for the
-next frame. After detecting a set bit, the chip neatly waits
-till the start of a frame, captures it and it goes back to off.
-Smart ppl will notice the problem here. Its the waiting on the
-_next_ frame each time we set the GRAB bit... Oh well, 12,5 fps
-is still plenty fast for me.
--- update 28/7/1999 --
-Don't believe a word I just said... Proof is the output
-of `streamer -t 300 -r 25 -f avi15 -o /dev/null`

-	syncer: done
-	writer: done
-(note the /dev/null is prudent here, my system is not able to
- grab /and/ write 25 fps to a file... gifts welcome :) )
-The technical reasoning follows: The zoran completed the last
-frame, the VSYNC goes low, and GRAB is cleared. The interrupt
-routine starts to work since its VSYNC driven, and again
-activates the GRAB bit. A few ms later the VSYNC (re-)rises and
-the zoran starts to work on a new and freshly broadcasted frame....
-
-For pointers I used the specs of both chips. Below are the URLs:
-  http://www.zoran.com/ftp/download/devices/pci/ZR36120/36120data.pdf
-  http://www-us.semiconductor.philips.com/acrobat/datasheets/SAA_7110_A_1.pdf
-Some alternatives for the Philips SAA 7110 datasheet are:
-  http://www.datasheetcatalog.com/datasheets_pdf/S/A/A/7/SAA7110.shtml
-  http://www.datasheetarchive.com/search.php?search=SAA7110&sType=part
-
-The documentation has very little on absolute numbers or timings
-needed for the various modes/resolutions, but there are other
-programs you can borrow those from.
-
------- Install --------------------------------------------
-Read the file called TODO.  Note its long list of limitations.
-
-Build a kernel with VIDEO4LINUX enabled. Activate the
-BT848 driver; we need this because we have need for the
-other modules (i2c and videodev) it enables.
-
-To install this software, extract it into a suitable directory.
-Examine the makefile and change anything you don't like.  Type "make".
-
-After making the modules check if you have the much needed
-/dev/video devices. If not, execute the following 4 lines:
-	mknod /dev/video c 81 0
-	mknod /dev/video1 c 81 1
-	mknod /dev/video2 c 81 2
-	mknod /dev/video3 c 81 3
-	mknod /dev/video4 c 81 4
-
-After making/checking the devices do:
-	modprobe i2c
-	modprobe videodev
-	modprobe saa7110	(optional)
-	modprobe saa7111	(optional)
-	modprobe tuner		(optional)
-	insmod zoran cardtype=<n>
-
-<n> is the cardtype of the card you have. The cardnumber can
-be found in the source of zr36120. Look for tvcards. If your
-card is not there, please try if any other card gives some
-response, and mail me if you got a working tvcard addition.
-
-PS. <TVCard editors behold!)
-    Don't forget to set video_input to the number of inputs
-    you defined in the video_mux part of the tvcard definition.
-    It's a common error to add a channel but not incrementing
-    video_input and getting angry with me/v4l/linux/linus :(
-
-You are now ready to test the framegrabber with your favorite
-video4linux compatible tool
-
------- Application ----------------------------------------
-
-This device works with all Video4Linux compatible applications,
-given the limitations in the TODO file.
-
------- API ------------------------------------------------
-
-This uses the V4L interface as of kernel release 2.1.116, and in
-fact has not been tested on any lower version.  There are a couple
-of minor differences due to the fact that the amount of data returned
-with each frame varies, and no doubt there are discrepancies due to my
-misunderstanding of the API.  I intend to convert this driver to the
-new V4L2 API when it has stabilized more.
-
------- Current state --------------------------------------
-
-The driver is capable of overlaying a video image in screen, and
-even capable of grabbing frames. It uses the BIGPHYSAREA patch
-to allocate lots of large memory blocks when tis patch is
-found in the kernel, but it doesn't need it.
-The consequence is that, when loading the driver as a module,
-the module may tell you it's out of memory, but 'free' says
-otherwise. The reason is simple; the modules wants its memory
-contiguous, not fragmented, and after a long uptime there
-probably isn't a fragment of memory large enough...
-
-The driver uses a double buffering scheme, which should really
-be an n-way buffer, depending on the size of allocated framebuffer
-and the requested grab-size/format.
-This current version also fixes a dead-lock situation during irq
-time, which really, really froze my system... :)
-
-Good luck.

-	  APM is a BIOS specification for saving power using several different
-	  techniques. This is mostly useful for battery powered laptops with
-	  APM compliant BIOSes. If you say Y here, the system time will be
-	  reset after a RESUME operation, the /proc/apm device will provide
-	  battery status information, and user-space programs will receive
-	  notification of APM "events" (e.g. battery status change).
-

-	  Battery Powered Linux mini-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>.
-
-	  This driver does not spin down disk drives (see the hdparm(8)
-	  manpage ("man 8 hdparm") for that), and it doesn't turn off
-	  VESA-compliant "green" monitors.
-
-	  Generally, if you don't have a battery in your machine, there isn't
-	  much point in using this driver and you should say N. If you get
-	  random kernel OOPSes or reboots that don't seem to be related to
-	  anything, try disabling/enabling this option (or disabling/enabling

+	help
+	  This gives the physical address where the kernel is loaded.
+
+	  If kernel is a not relocatable (CONFIG_RELOCATABLE=n) then
+	  bzImage will decompress itself to above physical address and
+	  run from there. Otherwise, bzImage will run from the address where
+	  it has been loaded by the boot loader and will ignore above physical
+	  address.
+
+	  In normal kdump cases one does not have to set/change this option
+	  as now bzImage can be compiled as a completely relocatable image
+	  (CONFIG_RELOCATABLE=y) and be used to load and run from a different
+	  address. This option is mainly useful for the folks who don't want
+	  to use a bzImage for capturing the crash dump and want to use a
+	  vmlinux instead. vmlinux is not relocatable hence a kernel needs
+	  to be specifically compiled to run from a specific memory area
+	  (normally a reserved region) and this option comes handy.
+
+	  So if you are using bzImage for capturing the crash dump, leave
+	  the value here unchanged to 0x100000 and set CONFIG_RELOCATABLE=y.
+	  Otherwise if you plan to use vmlinux for capturing the crash dump
+	  change this value to start of the reserved region (Typically 16MB
+	  0x1000000). In other words, it can be set based on the "X" value as
+	  specified in the "crashkernel=YM@XM" command line boot parameter
+	  passed to the panic-ed kernel. Typically this parameter is set as
+	  crashkernel=64M@16M. Please take a look at
+	  Documentation/kdump/kdump.txt for more details about crash dumps.
+
+	  Usage of bzImage for capturing the crash dump is recommended as
+	  one does not have to build two kernels. Same kernel can be used
+	  as production kernel and capture kernel. Above option should have
+	  gone away after relocatable bzImage support is introduced. But it
+	  is present because there are users out there who continue to use
+	  vmlinux for dump capture. This option should go away down the
+	  line.
+
+	  Don't change this unless you know what you are doing.

-	  APM is a BIOS specification for saving power using several different
-	  techniques. This is mostly useful for battery powered systems with
-	  APM compliant BIOSes. If you say Y here, the system time will be
-	  reset after a RESUME operation, the /proc/apm device will provide
-	  battery status information, and user-space programs will receive
-	  notification of APM "events" (e.g. battery status change).
-
-	  In order to use APM, you will need supporting software. For location
-	  and more information, read <file:Documentation/pm.txt> and the
-	  Battery Powered Linux mini-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>.
-
-	  This driver does not spin down disk drives (see the hdparm(8)
-	  manpage ("man 8 hdparm") for that), and it doesn't turn off
-	  VESA-compliant "green" monitors.
-
-	  Generally, if you don't have a battery in your machine, there isn't
-	  much point in using this driver and you should say N. If you get
-	  random kernel OOPSes or reboots that don't seem to be related to
-	  anything, try disabling/enabling this option (or disabling/enabling
-	  APM in your BIOS).

+ * The HV supports 256 plugs per thread, assigned as {0..255}, for a total

+ * implementation equates HV plug value to Linux virq value, constrains each
+ * interrupt to have a system wide unique plug number, and limits the range
+ * of the plug values to map into the first dword of the bitmaps.  This

+ *
+ * IBMACPI_FAN_RD_ACPI_GFAN:
+ * 	ACPI GFAN method: returns fan level
+ *
+ * 	see IBMACPI_FAN_WR_ACPI_SFAN
+ * 	EC 0x2f not available if GFAN exists
+ *
+ * IBMACPI_FAN_WR_ACPI_SFAN:
+ * 	ACPI SFAN method: sets fan level, 0 (stop) to 7 (max)
+ *
+ * 	EC 0x2f might be available *for reading*, but never for writing.
+ *
+ * IBMACPI_FAN_WR_TPEC:
+ * 	ThinkPad EC register 0x2f (HFSP): fan control loop mode Supported
+ * 	on almost all ThinkPads
+ *
+ * 	Fan speed changes of any sort (including those caused by the
+ * 	disengaged mode) are usually done slowly by the firmware as the
+ * 	maximum ammount of fan duty cycle change per second seems to be
+ * 	limited.
+ *
+ * 	Reading is not available if GFAN exists.
+ * 	Writing is not available if SFAN exists.
+ *
+ * 	Bits
+ *	 7	automatic mode engaged;
+ *  		(default operation mode of the ThinkPad)
+ * 		fan level is ignored in this mode.
+ *	 6	disengage mode (takes precedence over bit 7);
+ *		not available on all thinkpads.  May disable
+ *		the tachometer, and speeds up fan to 100% duty-cycle,
+ *		which speeds it up far above the standard RPM
+ *		levels.  It is not impossible that it could cause
+ *		hardware damage.
+ *	5-3	unused in some models.  Extra bits for fan level
+ *		in others, but still useless as all values above
+ *		7 map to the same speed as level 7 in these models.
+ *	2-0	fan level (0..7 usually)
+ *			0x00 = stop
+ * 			0x07 = max (set when temperatures critical)
+ * 		Some ThinkPads may have other levels, see
+ * 		IBMACPI_FAN_WR_ACPI_FANS (X31/X40/X41)
+ *
+ *	FIRMWARE BUG: on some models, EC 0x2f might not be initialized at
+ *	boot. Apparently the EC does not intialize it, so unless ACPI DSDT
+ *	does so, its initial value is meaningless (0x07).
+ *
+ *	For firmware bugs, refer to:
+ *	http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
+ *
+ * 	----
+ *
+ *	ThinkPad EC register 0x84 (LSB), 0x85 (MSB):
+ *	Main fan tachometer reading (in RPM)
+ *
+ *	This register is present on all ThinkPads with a new-style EC, and
+ *	it is known not to be present on the A21m/e, and T22, as there is
+ *	something else in offset 0x84 according to the ACPI DSDT.  Other
+ *	ThinkPads from this same time period (and earlier) probably lack the
+ *	tachometer as well.
+ *
+ *	Unfortunately a lot of ThinkPads with new-style ECs but whose firwmare
+ *	was never fixed by IBM to report the EC firmware version string
+ *	probably support the tachometer (like the early X models), so
+ *	detecting it is quite hard.  We need more data to know for sure.
+ *
+ *	FIRMWARE BUG: always read 0x84 first, otherwise incorrect readings
+ *	might result.
+ *
+ *	FIRMWARE BUG: when EC 0x2f bit 6 is set (disengaged mode), this
+ *	register is not invalidated in ThinkPads that disable tachometer
+ *	readings.  Thus, the tachometer readings go stale.
+ *
+ *	For firmware bugs, refer to:
+ *	http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
+ *
+ * IBMACPI_FAN_WR_ACPI_FANS:
+ *	ThinkPad X31, X40, X41.  Not available in the X60.
+ *
+ *	FANS ACPI handle: takes three arguments: low speed, medium speed,
+ *	high speed.  ACPI DSDT seems to map these three speeds to levels
+ *	as follows: STOP LOW LOW MED MED HIGH HIGH HIGH HIGH
+ *	(this map is stored on FAN0..FAN8 as "0,1,1,2,2,3,3,3,3")
+ *
+ * 	The speeds are stored on handles
+ * 	(FANA:FAN9), (FANC:FANB), (FANE:FAND).
+ *
+ * 	There are three default speed sets, acessible as handles:
+ * 	FS1L,FS1M,FS1H; FS2L,FS2M,FS2H; FS3L,FS3M,FS3H
+ *
+ * 	ACPI DSDT switches which set is in use depending on various
+ * 	factors.
+ *
+ * 	IBMACPI_FAN_WR_TPEC is also available and should be used to
+ * 	command the fan.  The X31/X40/X41 seems to have 8 fan levels,

+	  A human interface device (HID) is a type of computer device that

+	  designed using HID specification (this involves certain keyboards,
+	  mice, tablets, etc). This option compiles into kernel the generic
+	  HID layer code (parser, usages, etc.), which can then be used by
+	  transport-specific HID implementation (like USB or Bluetooth).

+ *  Basic support for Delkin/ASKA/Workbit Cardbus CompactFlash adapter

+ *  Modeled after the 16-bit PCMCIA driver: ide-cs.c
+ *
+ *  This is slightly peculiar, in that it is a PCI driver,

+ *  On the plus side, the driver is also smaller/simpler this way.

+ * - fix the clock turnaround code: it was writing to the wrong ports when
+ *   called for the secondary channel, caching the current clock mode per-
+ *   channel caused the cached register value to get out of sync with the
+ *   actual one, the channels weren't serialized, the turnaround shouldn't
+ *   be done on 66 MHz PCI bus
+ * - disable UltraATA/100 for HPT370 by default as the 33 MHz clock being used
+ *   does not allow for this speed anyway
+ * - avoid touching disabled channels (e.g. HPT371/N are single channel chips,
+ *   their primary channel is kind of virtual, it isn't tied to any pins)
+ * - fix/remove bad/unused timing tables and use one set of tables for the whole
+ *   HPT37x chip family; save space by introducing the separate transfer mode
+ *   table in which the mode lookup is done
+ * - use f_CNT value saved by  the HighPoint BIOS as reading it directly gives
+ *   the wrong PCI frequency since DPLL has already been calibrated by BIOS
+ * - fix the hotswap code:  it caused RESET- to glitch when tristating the bus,
+ *   and for HPT36x the obsolete HDIO_TRISTATE_HWIF handler was called instead
+ * - pass to init_chipset() handlers a copy of the IDE PCI device structure as
+ *   they tamper with its fields
+ * - pass  to the init_setup handlers a copy of the ide_pci_device_t structure
+ *   since they may tamper with its fields
+ * - prefix the driver startup messages with the real chip name
+ * - claim the extra 240 bytes of I/O space for all chips
+ * - optimize the rate masking/filtering and the drive list lookup code
+ * - use pci_get_slot() to get to the function 1 of HPT36x/374
+ * - cache offset of the channel's misc. control registers (MCRs) being used
+ *   throughout the driver
+ * - only touch the relevant MCR when detecting the cable type on HPT374's
+ *   function 1
+ * - rename all the register related variables consistently
+ * - move all the interrupt twiddling code from the speedproc handlers into
+ *   init_hwif_hpt366(), also grouping all the DMA related code together there
+ * - merge two HPT37x speedproc handlers, fix the PIO timing register mask and
+ *   separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
+ *   when setting an UltraDMA mode
+ * - fix hpt3xx_tune_drive() to set the PIO mode requested, not always select
+ *   the best possible one
+ * - clean up DMA timeout handling for HPT370
+ * - switch to using the enumeration type to differ between the numerous chip
+ *   variants, matching PCI device/revision ID with the chip type early, at the
+ *   init_setup stage
+ * - extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
+ *   stop duplicating it for each channel by storing the pointer in the pci_dev
+ *   structure: first, at the init_setup stage, point it to a static "template"
+ *   with only the chip type and its specific base DPLL frequency, the highest
+ *   supported DMA mode, and the chip settings table pointer filled, then, at
+ *   the init_chipset stage, allocate per-chip instance  and fill it with the
+ *   rest of the necessary information
+ * - get rid of the constant thresholds in the HPT37x PCI clock detection code,
+ *   switch  to calculating  PCI clock frequency based on the chip's base DPLL
+ *   frequency
+ * - switch to using the  DPLL clock and enable UltraATA/133 mode by default on
+ *   anything  newer than HPT370/A
+ * - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
+ *   also fixing the interchanged 25/40 MHz PCI clock cases for HPT36x chips;
+ *   unify HPT36x/37x timing setup code and the speedproc handlers by joining

+	  Support hosting fully virtualized guest machines using hardware
+	  virtualization extensions.  You will need a fairly recent
+	  processor equipped with virtualization extensions. You will also
+	  need to select one or more of the processor modules below.
+
+	  This module provides access to the hardware capabilities through
+	  a character device node named /dev/kvm.
+
+	  To compile this as a module, choose M here: the module
+	  will be called kvm.
+
+	  If unsure, say N.

+ * x86_emulate_ops:
+ *
+ * These operations represent the instruction emulator's interface to memory.
+ * There are two categories of operation: those that act on ordinary memory
+ * regions (*_std), and those that act on memory regions known to require
+ * special treatment or emulation (*_emulated).
+ *
+ * The emulator assumes that an instruction accesses only one 'emulated memory'
+ * location, that this location is the given linear faulting address (cr2), and
+ * that this is one of the instruction's data operands. Instruction fetches and
+ * stack operations are assumed never to access emulated memory. The emulator
+ * automatically deduces which operand of a string-move operation is accessing
+ * emulated memory, and assumes that the other operand accesses normal memory.
+ *
+ * NOTES:
+ *  1. The emulator isn't very smart about emulated vs. standard memory.
+ *     'Emulated memory' access addresses should be checked for sanity.
+ *     'Normal memory' accesses may fault, and the caller must arrange to
+ *     detect and handle reentrancy into the emulator via recursive faults.
+ *     Accesses may be unaligned and may cross page boundaries.
+ *  2. If the access fails (cannot emulate, or a standard access faults) then
+ *     it is up to the memop to propagate the fault to the guest VM via
+ *     some out-of-band mechanism, unknown to the emulator. The memop signals
+ *     failure by returning X86EMUL_PROPAGATE_FAULT to the emulator, which will
+ *     then immediately bail.
+ *  3. Valid access sizes are 1, 2, 4 and 8 bytes. On x86/32 systems only
+ *     cmpxchg8b_emulated need support 8-byte accesses.
+ *  4. The emulator cannot handle 64-bit mode emulation on an x86/32 system.

+ * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &
+ * Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink
+ * Updates to driver completed by Dwaine P. Garden
+ *
+ *
+ * TODO:
+ *     - use submit_urb for all setup packets
+ *     - Fix memory settings for nt1004. It is 4 times as big as the
+ *       nt1003 memory.
+ *     - Add audio on endpoint 3 for nt1004 chip.  Seems impossible, needs a codec interface.  Which one?
+ *     - Clean up the driver.
+ *     - optimization for performance.
+ *     - Add Videotext capability (VBI).  Working on it.....
+ *     - Check audio for other devices

-
-  A big thank you to the S&K support for providing me so quickly with
-  documentation!
-
-  Also see http://www.syskonnect.com/
-
-  Missing things:
-
-  -> set debug level via ioctl instead of compile-time switches
-  -> I didn't follow the development of the 2.1.x kernels, so my
-     assumptions about which things changed with which kernel version
-     are probably nonsense
-
-History:
-  May 16th, 1999
-  	startup
-  May 22st, 1999
-	added private structure, methods
-        begun building data structures in RAM
-  May 23nd, 1999
-	can receive frames, send frames
-  May 24th, 1999
-        modularized initialization of LANCE
-        loadable as module
-	still Tx problem :-(
-  May 26th, 1999
-  	MC2 works
-  	support for multiple devices
-  	display media type for MC2+
-  May 28th, 1999
-	fixed problem in GetLANCE leaving interrupts turned off
-        increase TX queue to 4 packets to improve send performance
-  May 29th, 1999
-	a few corrections in statistics, caught rcvr overruns
-        reinitialization of LANCE/board in critical situations
-        MCA info implemented
-	implemented LANCE multicast filter
-  Jun 6th, 1999
-	additions for Linux 2.2
-  Dec 25th, 1999
-  	unfortunately there seem to be newer MC2+ boards that react
-  	on IRQ 3/5/9/10 instead of 3/5/10/11, so we have to autoprobe
-  	in questionable cases...
-  Dec 28th, 1999
-	integrated patches from David Weinehall & Bill Wendling for 2.3
-	kernels (isa_...functions).  Things are defined in a way that
-        it still works with 2.0.x 8-)
-  Dec 30th, 1999
-	added handling of the remaining interrupt conditions.  That
-        should cure the spurious hangs.
-  Jan 30th, 2000
-	newer kernels automatically probe more than one board, so the
-	'startslot' as a variable is also needed here
-  June 1st, 2000
-	added changes for recent 2.3 kernels

- *          receive. You must identify completely the message to
- *          which you wish to reply. ie, pathid, msgid, and trgcls.
- *          The array identifies a list of addresses and lengths of
- *          discontiguous buffers that contains the reply data.
- * Input: pathid - Path identification number
- *        msgid - Specifies the message ID.
- *        trgcls - Specifies target class.
- *        flags1 - Option for path.
- *          IPPRTY- 0x20, Specifies if you want to send priority message.
- *        buffer - Address of array of reply buffers.
- *        buflen - Total length of reply buffers.
- * Output: residual_buffer - Address of buffer which IUCV is currently working on.
- *         residual_length - Contains one of the following values:
- *              If the answer buffer is the same length as the reply, this field
- *               contains zero.
- *              If the answer buffer is longer than the reply, this field contains
- *               the number of bytes remaining in the buffer.
- *              If the answer buffer is shorter than the reply, this field contains
- *               a residual count (that is, the number of bytes remianing in the
- *               reply that does not fit into the buffer. In this
- *               case b2f0_result = 5.
- * Return: Return code from CP IUCV call.

  * OHCI is the main "non-Intel/VIA" standard for USB 1.1 host controller
  * interfaces (though some non-x86 Intel chips use it).  It supports
  * smarter hardware than UHCI.  A download link for the spec available
  * through the http://www.usb.org website.
  *
- * History:
- * 
- * 2004/03/24 LH7A404 support (Durgesh Pattamatta & Marc Singer)
- * 2004/02/04 use generic dma_* functions instead of pci_* (dsaxena@plexity.net)
- * 2003/02/24 show registers in sysfs (Kevin Brosius)
- *
- * 2002/09/03 get rid of ed hashtables, rework periodic scheduling and
- * 	bandwidth accounting; if debugging, show schedules in driverfs
- * 2002/07/19 fixes to management of ED and schedule state.
- * 2002/06/09 SA-1111 support (Christopher Hoover)
- * 2002/06/01 remember frame when HC won't see EDs any more; use that info
- *	to fix urb unlink races caused by interrupt latency assumptions;
- *	minor ED field and function naming updates
- * 2002/01/18 package as a patch for 2.5.3; this should match the
- *	2.4.17 kernel modulo some bugs being fixed.
- *
- * 2001/10/18 merge pmac cleanup (Benjamin Herrenschmidt) and bugfixes
- *	from post-2.4.5 patches.
- * 2001/09/20 URB_ZERO_PACKET support; hcca_dma portability, OPTi warning
- * 2001/09/07 match PCI PM changes, errnos from Linus' tree
- * 2001/05/05 fork 2.4.5 version into "hcd" framework, cleanup, simplify;
- *	pbook pci quirks gone (please fix pbook pci sw!) (db)
- *
- * 2001/04/08 Identify version on module load (gb)
- * 2001/03/24 td/ed hashing to remove bus_to_virt (Steve Longerbeam);
- 	pci_map_single (db)
- * 2001/03/21 td and dev/ed allocation uses new pci_pool API (db)
- * 2001/03/07 hcca allocation uses pci_alloc_consistent (Steve Longerbeam)
- *
- * 2000/09/26 fixed races in removing the private portion of the urb
- * 2000/09/07 disable bulk and control lists when unlinking the last
- *	endpoint descriptor in order to avoid unrecoverable errors on
- *	the Lucent chips. (rwc@sgi)
- * 2000/08/29 use bandwidth claiming hooks (thanks Randy!), fix some
- *	urb unlink probs, indentation fixes
- * 2000/08/11 various oops fixes mostly affecting iso and cleanup from
- *	device unplugs.
- * 2000/06/28 use PCI hotplug framework, for better power management
- *	and for Cardbus support (David Brownell)
- * 2000/earlier:  fixes for NEC/Lucent chips; suspend/resume handling
- *	when the controller loses power; handle UE; cleanup; ...
- *
- * v5.2 1999/12/07 URB 3rd preview,

- *  This header file defines assembler macros of the form:
- *	<x>cache_<func>
- *  where <x> is 'i' or 'd' for instruction and data caches,
- *  and <func> indicates the function of the macro.
- *
- *  The following functions <func> are defined,
- *  and apply only to the specified cache (I or D):
- *
- *  reset
- *	Resets the cache.
- *
- *  sync
- *	Makes sure any previous cache instructions have been completed;
- *	ie. makes sure any previous cache control operations
- *	have had full effect and been synchronized to memory.
- *	Eg. any invalidate completed [so as not to generate a hit],
- *	any writebacks or other pipelined writes written to memory, etc.
- *
- *  invalidate_line		(single cache line)
- *  invalidate_region		(specified memory range)
- *  invalidate_all		(entire cache)
- *	Invalidates all cache entries that cache
- *	data from the specified memory range.
- *	NOTE: locked entries are not invalidated.
- *
- *  writeback_line		(single cache line)
- *  writeback_region		(specified memory range)
- *  writeback_all		(entire cache)
- *	Writes back to memory all dirty cache entries
- *	that cache data from the specified memory range,
- *	and marks these entries as clean.
- *	NOTE: on some future implementations, this might
- *		also invalidate.
- *	NOTE: locked entries are written back, but never invalidated.
- *	NOTE: instruction caches never implement writeback.
- *
- *  writeback_inv_line		(single cache line)
- *  writeback_inv_region	(specified memory range)
- *  writeback_inv_all		(entire cache)
- *	Writes back to memory all dirty cache entries
- *	that cache data from the specified memory range,
- *	and invalidates these entries (including all clean
- *	cache entries that cache data from that range).
- *	NOTE: locked entries are written back but not invalidated.
- *	NOTE: instruction caches never implement writeback.
- *
- *  lock_line			(single cache line)
- *  lock_region			(specified memory range)
- *	Prefetch and lock the specified memory range into cache.
- *	NOTE:  if any part of the specified memory range cannot
- *	be locked, a ??? exception occurs.  These macros don't
- *	do anything special (yet anyway) to handle this situation.
- *
- *  unlock_line			(single cache line)
- *  unlock_region		(specified memory range)
- *  unlock_all			(entire cache)
- *	Unlock cache entries that cache the specified memory range.
- *	Entries not already locked are unaffected.

- *  The following macros assume the following cache size/parameter limits
- *  in the current Xtensa core implementation:
- *	cache size:	1024 bytes minimum
- *	line size:	16 - 64 bytes
- *	way count:	1 - 4
- *
- *  Minimum entries per way (ie. per associativity) = 1024 / 64 / 4 = 4
- *  Hence the assumption that each loop can execute four cache instructions.
- *
- *  Correspondingly, the offset range of instructions is assumed able to cover
- *  four lines, ie. offsets {0,1,2,3} * line_size are assumed valid for
- *  both hit and indexed cache instructions.  Ie. these offsets are all
- *  valid:  0, 16, 32, 48, 64, 96, 128, 192 (for line sizes 16, 32, 64).
- *  This is true of all original cache instructions
- *  (dhi, ihi, dhwb, dhwbi, dii, iii) which have offsets
- *  of 0 to 1020 in multiples of 4 (ie. 8 bits shifted by 2).
- *  This is also true of subsequent cache instructions
- *  (dhu, ihu, diu, iiu, diwb, diwbi, dpfl, ipfl) which have offsets
- *  of 0 to 240 in multiples of 16 (ie. 4 bits shifted by 4).
- *
- *  (Maximum cache size, currently 32k, doesn't affect the following macros.
- *  Cache ways > MMU min page size cause aliasing but that's another matter.)

-/*
- *  General notes on MMU parameters.
- *
- *  Terminology:
- *	ASID = address-space ID (acts as an "extension" of virtual addresses)
- *	VPN  = virtual page number
- *	PPN  = physical page number
- *	CA   = encoded cache attribute (access modes)
- *	TLB  = translation look-aside buffer (term is stretched somewhat here)
- *	I    = instruction (fetch accesses)
- *	D    = data (load and store accesses)
- *	way  = each TLB (ITLB and DTLB) consists of a number of "ways"
- *		that simultaneously match the virtual address of an access;
- *		a TLB successfully translates a virtual address if exactly
- *		one way matches the vaddr; if none match, it is a miss;
- *		if multiple match, one gets a "multihit" exception;
- *		each way can be independently configured in terms of number of
- *		entries, page sizes, which fields are writable or constant, etc.
- *	set  = group of contiguous ways with exactly identical parameters
- *	ARF  = auto-refill; hardware services a 1st-level miss by loading a PTE
- *		from the page table and storing it in one of the auto-refill ways;
- *		if this PTE load also misses, a miss exception is posted for s/w.
- *	min-wired = a "min-wired" way can be used to map a single (minimum-sized)
- * 		page arbitrarily under program control; it has a single entry,
- *		is non-auto-refill (some other way(s) must be auto-refill),
- *		all its fields (VPN, PPN, ASID, CA) are all writable, and it
- *		supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
- *		restriction is that this be the only page size it supports).
- *
- *  TLB way entries are virtually indexed.
- *  TLB ways that support multiple page sizes:
- *	- must have all writable VPN and PPN fields;
- *	- can only use one page size at any given time (eg. setup at startup),
- *	  selected by the respective ITLBCFG or DTLBCFG special register,
- *	  whose bits n*4+3 .. n*4 index the list of page sizes for way n
- *	  (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
- *	  this list may be sparse for auto-refill ways because auto-refill
- *	  ways have independent lists of supported page sizes sharing a
- *	  common encoding with PTE entries; the encoding is the index into
- *	  this list; unsupported sizes for a given way are zero in the list;
- *	  selecting unsupported sizes results in undefined hardware behaviour;
- *	- is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).

- *  find_ms_setbit
- *
- *  This macro finds the most significant bit that is set in <as>

- *  The index counts starting at zero for the lsbit, so the return

- *
- *  Parameters:
- *	<ad>	destination address register (any register)
- *	<as>	source address register
- *	<at>	temporary address register (must be different than <as>)
- *	<base>	constant value added to result (usually 0 or 1)
- *  On entry:
- *	<ad> = undefined if different than <as>
- *	<as> = value whose most significant set bit is to be found
- *	<at> = undefined
- *	no other registers are used by this macro.

- *  floop, floopnez, floopgtz, floopend
- *
- *  These macros are used for fast inner loops that
- *  work whether or not the Loops options is configured.
- *  If the Loops option is configured, they simply use
- *  the zero-overhead LOOP instructions; otherwise
- *  they use explicit decrement and branch instructions.
- *
- *  They are used in pairs, with floop, floopnez or floopgtz
- *  at the beginning of the loop, and floopend at the end.
- *
- *  Each pair of loop macro calls must be given the loop count
- *  address register and a unique label for that loop.
- *
- *  Example:
- *
- *	movi	 a3, 16     // loop 16 times
- *	floop    a3, myloop1
- *	:
- *	bnez     a7, end1	// exit loop if a7 != 0
- *	:
- *	floopend a3, myloop1
- *  end1:
- *
- *  Like the LOOP instructions, these macros cannot be
- *  nested, must include at least one instruction,
- *  cannot call functions inside the loop, etc.
- *  The loop can be exited by jumping to the instruction
- *  following floopend (or elsewhere outside the loop),
- *  or continued by jumping to a NOP instruction placed
- *  immediately before floopend.
- *
- *  Unlike LOOP instructions, the register passed to floop*
- *  cannot be used inside the loop, because it is used as
- *  the loop counter if the Loops option is not configured.
- *  And its value is undefined after exiting the loop.
- *  And because the loop counter register is active inside
- *  the loop, you can't easily use this construct to loop
- *  across a register file using ROTW as you might with LOOP
- *  instructions, unless you copy the loop register along.

- *  window_spill{4,8,12}
- *
- *  These macros spill callers' register windows to the stack.
- *  They work for both privileged and non-privileged tasks.
- *  Must be called from a windowed ABI context, eg. within
- *  a windowed ABI function (ie. valid stack frame, window
- *  exceptions enabled, not in exception mode, etc).
- *
- *  This macro requires a single invocation of the window_spill_common
- *  macro in the same assembly unit and section.
- *
- *  Note that using window_spill{4,8,12} macros is more efficient
- *  than calling a function implemented using window_spill_function,
- *  because the latter needs extra code to figure out the size of
- *  the call to the spilling function.
- *
- *  Example usage:
- *
- *		.text
- *		.align	4
- *		.global	some_function
- *		.type	some_function,@function
- *	some_function:
- *		entry	a1, 16
- *		:
- *		:
- *
- *		window_spill4	// spill windows of some_function's callers; preserves a0..a3 only;
- *				// to use window_spill{8,12} in this example function we'd have
- *				// to increase space allocated by the entry instruction, because
- *				// 16 bytes only allows call4; 32 or 48 bytes (+locals) are needed
- *				// for call8/window_spill8 or call12/window_spill12 respectively.
- *		:
- *
- *		retw
- *
- *		window_spill_common	// instantiates code used by window_spill4
- *
- *
- *  On entry:
- *	none (if window_spill4)
- *	stack frame has enough space allocated for call8 (if window_spill8)
- *	stack frame has enough space allocated for call12 (if window_spill12)
- *  On exit:

- *  A bit of software release history on values of XTHAL_{MAJOR,MINOR}_REV:
- *
- *	Release		MAJOR	MINOR		Comment
- *	=======		=====	=====		=======
- *	T1015.n		n/a	n/a		(HAL not yet available)
- *	T1020.{0,1,2}	0	1		(HAL beta)
- *	T1020.{3,4}	0	2		First release.
- *	T1020.n (n>4)	0	2 or >3		(TBD)
- *	T1030.0		0	1		(HAL beta)
- *	T1030.{1,2}	0	3		Equivalent to first release.
- *	T1030.n (n>=3)	0	>= 3		(TBD)
- *	T1040.n		1040	n		Full CHAL available from T1040.2
- *	T1050.n		1050	n		Current release.
- *
- *
- *  Note:  there is a distinction between the software release with
- *  which something is compiled (accessible using XTHAL_RELEASE_* macros)
- *  and the software release with which the HAL library was compiled
- *  (accessible using Xthal_release_* global variables).  This
- *  distinction is particularly relevant for vendors that distribute
- *  configuration-independent binaries (eg. an OS), where their customer
- *  might link it with a HAL of a different Xtensa software release.
- *  In this case, it may be appropriate for the OS to verify at run-time
- *  whether XTHAL_RELEASE_* and Xthal_release_* are compatible.
- *  [Guidelines as to which release is compatible with which are not
- *  currently provided explicitly, but might be inferred from reading
- *  OSKit documentation for all releases -- compatibility is also highly
- *  dependent on which HAL features are used.  Each release is usually
- *  backward compatible, with very few exceptions if any.]
- *
- *  Notes:
- *	Tornado 2.0 supported in T1020.3+, T1030.1+, and T1040.{0,1} only.
- *	Tornado 2.0.2 supported in T1040.2+, and T1050.
- *	Compile-time HAL port of NucleusPlus supported by T1040.2+ and T1050.

- *  (eg. files accessed are those of the simulator host).
- *  However, these SIMCALLs model a virtual operating system

- *  Device addresses.

- *  Note:  for endianness-independence, use 32-bit loads and stores for all
- *  register accesses to Ethernet, DUART and LED devices.  Undefined bits
- *  may need to be masked out if needed when reading if the actual register
- *  size is smaller than 32 bits.
- *
- *  Note:  XT2000 bus byte lanes are defined in terms of msbyte and lsbyte
- *  relative to the processor.  So 32-bit registers are accessed consistently
- *  from both big and little endian processors.  However, this means byte
- *  sequences are not consistent between big and little endian processors.
- *  This is fine for RAM, and for ROM if ROM is created for a specific
- *  processor (and thus has correct byte sequences).  However this may be
- *  unexpected for Flash, which might contain a file-system that one wants
- *  to use for multiple processor configurations (eg. the Flash might contain
- *  the Ethernet card's address, endianness-independent application data, etc).
- *  That is, byte sequences written in Flash by a core of a given endianness
- *  will be byte-swapped when seen by a core of the other endianness.
- *  Someone implementing an endianness-independent Flash file system will
- *  likely handle this byte-swapping issue in the Flash driver software.

+	  APM is a BIOS specification for saving power using several different
+	  techniques. This is mostly useful for battery powered laptops with
+	  APM compliant BIOSes. If you say Y here, the system time will be
+	  reset after a RESUME operation, the /proc/apm device will provide
+	  battery status information, and user-space programs will receive
+	  notification of APM "events" (e.g. battery status change).
+
+	  In order to use APM, you will need supporting software. For location
+	  and more information, read <file:Documentation/pm.txt> and the
+	  Battery Powered Linux mini-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>.
+
+	  This driver does not spin down disk drives (see the hdparm(8)
+	  manpage ("man 8 hdparm") for that), and it doesn't turn off
+	  VESA-compliant "green" monitors.
+
+	  Generally, if you don't have a battery in your machine, there isn't
+	  much point in using this driver and you should say N. If you get
+	  random kernel OOPSes or reboots that don't seem to be related to
+	  anything, try disabling/enabling this option (or disabling/enabling
+	  APM in your BIOS).

+/*
+  Generic support for BUG()
+
+  This respects the following config options:
+
+  CONFIG_BUG - emit BUG traps.  Nothing happens without this.
+  CONFIG_GENERIC_BUG - enable this code.
+  CONFIG_DEBUG_BUGVERBOSE - emit full file+line information for each BUG
+
+  CONFIG_BUG and CONFIG_DEBUG_BUGVERBOSE are potentially user-settable
+  (though they're generally always on).
+
+  CONFIG_GENERIC_BUG is set by each architecture using this code.
+
+  To use this, your architecture must:
+
+  1. Set up the config options:
+     - Enable CONFIG_GENERIC_BUG if CONFIG_BUG
+
+  2. Implement BUG (and optionally BUG_ON, WARN, WARN_ON)
+     - Define HAVE_ARCH_BUG
+     - Implement BUG() to generate a faulting instruction
+     - NOTE: struct bug_entry does not have "file" or "line" entries
+       when CONFIG_DEBUG_BUGVERBOSE is not enabled, so you must generate
+       the values accordingly.
+
+  3. Implement the trap
+     - In the illegal instruction trap handler (typically), verify
+       that the fault was in kernel mode, and call report_bug()
+     - report_bug() will return whether it was a false alarm, a warning,
+       or an actual bug.
+     - You must implement the is_valid_bugaddr(bugaddr) callback which
+       returns true if the eip is a real kernel address, and it points
+       to the expected BUG trap instruction.

+/* PF_BRIDGE/LOCAL_OUT ***********************************************
+ *
+ * This function sees both locally originated IP packets and forwarded
  * IP packets (in both cases the destination device is a bridge
  * device). It also sees bridged-and-DNAT'ed packets.
- * To be able to filter on the physical bridge devices (with the physdev
- * module), we steal packets destined to a bridge device away from the
- * PF_INET/FORWARD and PF_INET/OUTPUT hook functions, and give them back later,
- * when we have determined the real output device. This is done in here.
  *
  * If (nf_bridge->mask & BRNF_BRIDGED_DNAT) then the packet is bridged
  * and we fake the PF_BRIDGE/FORWARD hook. The function br_nf_forward()
  * will then fake the PF_INET/FORWARD hook. br_nf_local_out() has priority
  * NF_BR_PRI_FIRST, so no relevant PF_BRIDGE/INPUT functions have been nor
  * will be executed.
- * Otherwise, if nf_bridge->physindev is NULL, the bridge-nf code never touched
- * this packet before, and so the packet was locally originated. We fake
- * the PF_INET/LOCAL_OUT hook.
- * Finally, if nf_bridge->physindev isn't NULL, then the packet was IP routed,
- * so we fake the PF_INET/FORWARD hook. ip_sabotage_out() makes sure
- * even routed packets that didn't arrive on a bridge interface have their
- * nf_bridge->physindev set. */

+	  connection (usually limiting it to your outgoing interface's MTU
+	  minus 40).

+	  This is used to overcome criminally braindead ISPs or servers which

+	  problem are that everything works fine from your Linux
+	  firewall/router, but machines behind it can never exchange large

+	        1) Web browsers connect, then hang with no data received.
+	        2) Small mail works fine, but large emails hang.
+	        3) ssh works fine, but scp hangs after initial handshaking.
+
+	  Workaround: activate this option and add a rule to your firewall
+	  configuration like:
+
+	  iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \

+ *
+ *  Revision history
+ *    12th Aug 2005   Initial version.
+ *    25th Oct 2005   Implemented path power domain.
+ *    18th Dec 2005   Implemented machine and stream level power domain.
+ *
+ *  Features:
+ *    o Changes power status of internal codec blocks depending on the
+ *      dynamic configuration of codec internal audio paths and active
+ *      DAC's/ADC's.
+ *    o Platform power domain - can support external components i.e. amps and
+ *      mic/meadphone insertion events.
+ *    o Automatic Mic Bias support
+ *    o Jack insertion power event initiation - e.g. hp insertion will enable
+ *      sinks, dacs, etc
+ *    o Delayed powerdown of audio susbsytem to reduce pops between a quick
+ *      device reopen.
+ *
+ *  Todo:
+ *    o DAPM power change sequencing - allow for configurable per
+ *      codec sequences.
+ *    o Support for analogue bias optimisation.
+ *    o Support for reduced codec oversampling rates.
+ *    o Support for reduced codec bias currents.
