Add generic abstract layer for display output switch control. The output
sysfs class driver provides an abstract video output layer that can be used to
hook platform specific methods to enable/disable video output device through
common sysfs interface.

Adds backlight support using backlight class. We now
change the brightness *and toggle the backlight !* via
/sys/class/backlight/asus-laptop/.
If the user switchs the backlight using the keyboard,
asus_hotk_notify looks for ATKD_LCD_OFF and ATKD_LCD_ON events,
and stores the right state into hotk->status and bd->props->power .

WLED and BLED are not handled like other leds (MLED, etc ..),
because sometime they also control the wlan/bluetooth device.
If the method for wireless_status is found, it's used to get the
status, otherwise hotk->status is used. We also use the HWRS
method, which tell if the bluetooth/wlan device is present or not.
This patch show why we need a ASUS_SET_DEVICE_ATTR macro : if
there is a bluetooth device, /sys/dev.../asus-laptop/bluetooth
is usable, else it's not but it's clean.

<http://lkml.org/lkml/2006/7/6/247> was very usefull. We use
hotk->status to store led status because it's very hard to find
acpi method to get the right status... To reduce the code,
I use a lot of macro (ASUS_LED, ASUS_LED_REGISTER, etc ...),
because the code is the same for all leds ...

and ASUS_SET_DEVICE_ATTR now, but these macro will be very

from IBM_HANDLE and IBM_HANDLE_INIT, with some modification,
and will also be used in next patchs.

The PNP system board driver (drivers/pnp/system.c) contains all the
same functionality, so we don't need the ACPI version.
Previously, a motherboard device would be claimed by *both* the ACPI and
PNP drivers, resulting in stuff like this in /proc/ioports:
1200-121f : motherboard <-- from drivers/acpi/motherboard.c
1200-121f : pnp 00:0d <-- from drivers/pnp/system.c
Make sure to enable CONFIG_PNP (and CONFIG_PNPACPI) to include the
PNP system board driver.

I'm trying to remove drivers/acpi/motherboard.c, which is mostly
redundant with drivers/pnp/system.c. So make sure that we include the
PNP driver in the default config. Most distros enable this already.
Turning on CONFIG_PNP also causes the following options to be enabled:
CONFIG_PNPACPI
CONFIG_SERIAL_8250_PNP
CONFIG_SERIAL_8250_PNP causes legacy serial ports to be discovered
twice, which is ugly but harmless:
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:07: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

Resources described by the FADT aren't really a good fit for the
ACPI motherboard driver.
The motherboard driver cares about PNP0C01 and PNP0C02 devices and
their resources.
The FADT describes some resources used by the ACPI core. Often, they
are also described by by the _CRS of a motherboard device, but I think
it's better to reserve them specifically in the ACPI osl.c because
(a) the motherboard driver is optional and ACPI uses the resources even
if the driver is absent, and (b) I want to remove the ACPI motherboard
driver because it's mostly redundant with the PNP system.c driver.

Some of the ACPI devices use the internal fake hids
which are exposed to userspace as devces' bus_id after sysfs conversion.
To make it more friendly, we convert them to more understandable strings.
For those devices w/o PNPids, we use "device:instance_no" as the bus_id
instead of "PNPIDNON:instance_no".

Originally we converted bind/unbind to use a new pci bridge driver.
The driver will add/remove _PRT, so we can eventually remove
.bind/.unbind methods.
But we found that some of the _ADR-Based devices don't have _PRT,
i.e. they are not managed by the new ACPI PCI bridge driver.
So that .bind method is not called for some _ADR-Based devices,
which leads to a failure.
Now we make ACPI PCI Root Bridge Driver scan and binds all _ADR-Based devices
once the driver is loaded, in the .add method of ACPI PCI Root Bridge driver.
Extra code path for calling .bind/.unbind when _ADR-Based devices
are hot added/removed is also added.

Previously we used the device name in the DSDT, but would
crash upon encountering a duplicate. Also, exposing the
DSDT device name to the user in a patch isn't a good idea,
because it is arbitrary.
After some discussion, we finally decided to use
"PNPID:instance_no" as the bus_id of ACPI devices.
Two attributes for each device are added at the same time,
the full pathname in ACPI namespace and hardware_id if it has.
NOTE: acpi_bus_id_list is used to keep the information of PNPID
and instance number of the given PNPID. Loop the
acpi_bus_id_list to find the instance_no of the same PNPID
when register a device. If failed, i.e. we don't have a
node with this PNPID, allocate one and link it to this list.
NOTE: Now I don't take the memory free work in charge.
If necessary, I can add a reference count in
struct acpi_device_bus_id, and check the reference and
when unregister a device, i.e. memory is freed when
the reference count of a given PNPID is 0.

We do this mainly because:
1. hid is used to match ACPI devices and drivers.
.match method which is incompatible to driver model
can be deleted from acpi_driver.ops then.
2. As the .uevent method mark ACPI drivers by PNPID,
fake hid is set to non-PNPID devices so that udev script
can load the right ACPI driver by looking for
"HWID = " or "COMPTID = ".

Add removal_type in structure acpi_device for hot removal.
ACPI_BUS_REMOVAL_EJECT is used for ACPI device hot removal.
Only one parameter is allowed in .remove method due to driver model.
So removal_type is added to indicate different removal type.

Add acpi_bus_ops in acpi_device to support acpi hot plug.
NOTE: Two methods .add and .start in acpi_driver.ops are
called separately to probe ACPI devices, while only
.probe method is called in driver model.
As executing .add and .start separately is critical
for ACPI device hot plug, we use acpi_bus_ops to
distinguish different code path.

Setup new sysfs framework
1. Remove /sys/firmware/acpi
2. Add ACPI device in device tree.
File "eject" for every device that has _EJ0 method is moved from
/sys/firmware to /sys/devices.
Operation on this file is exactly the same as before.
i.e. echo 1 to "eject" will cause hot removal of this device.
Corresponding changes should be made in userspace for hot removal.

Adjust link order to add ACPI devices to global list before PCI devices.
In addition, acpi_bus type must be initialized before any driver loads.

Add ACPI bus_type for Linux driver model.
1. .shutdown method is added into acpi_driver.ops
needed by bus_type operations.
2. remove useless parameter 'int state' in .resume method.
3. change parameter 'int state'
to 'pm_message_t state' in .suspend method.
Note: The new .uevent method mark ACPI drivers by PNPID instead of by name.
Udev script needs to look for "HWID=" or "COMPTID=" to load
ACPI drivers as a result.

We want the name 'to_acpi_device'.
And the current macro 'to_acpi_device' will be removed
after device model is setup.
So just simply rename them.

Adjust the code and make code doing similar things together.
No logic changes.
