With this patch, you'll get the following sysfs directories. This
structure implies that a single platform device, "omap2-mailbox" holds
multiple logical mbox instances. This could be the base to add sysfs
files for each logical mboxes. Then userland application can access a
mbox through sysfs entries if necessary(ex: setting kfifo size
dynamically)

The underlying buffering implementation of mailbox
is converted from block API to kfifo due to the simplicity
and speed of kfifo.
The default size of the kfifo buffer is set to 256 bytes.
This value is configurable at compile time (via
CONFIG_OMAP_MBOX_KFIFO_SIZE), and can be changed at
runtime (via the mbox_kfifo_size module parameter).

without read the message from the mailbox fifo, then when it
leaves the isr and interruption is trigger again and again and
the workqueue which get elements from the request queue is never

Additionally, update some of the CHIP_GE_* macros to use other

The only difference between them is the physical address of the

Add omap_pm_set_min_clk_rate(). This constraint is meant for use by
device drivers to translate a certain device-specific performance
constraint (e.g., "minimum polygons per second") to a clock rate for
the driver's device, given the driver's intimate knowledge of the
device hardware (e.g., device type, device hardware revision, firmware
revision, etc.) From a general PM core perspective, clock rate is
probably the closest general analog to "performance" that is
available, but the exact mapping from a use-case-specific performance
constraint to clock rate must be done by the driver. Drivers intended for
upstream merging shouldn't hardcode specific clock rates in their code
without basing those rates on some performance criteria requested through
the driver's subsystem (ideally, from userspace).
Imre Deak <imre.deak@nokia.com> described the need and use-case for
this constraint, and discussed the implementation - thanks, Imre.

omap_pm_set_max_dev_wakeup_lat()
Add return values to the PM constraint functions. This allows the PM
core to provide feedback to the caller if a constraint is not
possible. Update the one upstream user of omap_pm_set_max_mpu_wakeup_lat()
to add a compatibility wrapper, needed until the driver is changed.
Update some of the documentation to conform more closely to kerneldoc style.
Add an additional device parameter to omap_pm_set_max_dev_wakeup_lat()
to identify the device requesting the constraint. This is so repeated calls
to omap_pm_set_max_dev_wakeup_lat() with the same requesting device can
override the device's previously-set constraint. Also, it allows the PM
core to make a decision as to whether or not the constraint should be
satisfied, based on the caller's identity.

Add omap_device_get_mpu_rt_va(). This is intended to be used by
device drivers (currently, via a struct platform_data function
pointer) to retrieve their corresponding device's virtual base address
that the MPU should use to access the device. This is needed because
the omap_hwmod code does its own ioremap(), in order to gain access to
the module's OCP_SYSCONFIG register.
Add omap_hwmod_get_mpu_rt_va(). omap_device_get_mpu_rt_va() calls this
function to do the real work.
While here, rename struct omap_hwmod._rt_va to struct
omap_hwmod._mpu_rt_va, to reinforce that it refers to the MPU's
register target virtual address base (as opposed to, for example, the
L3's).
In the future, this belongs as a function in an omap_bus, so it is not
necessary to call this through a platform_data function pointer.
The use-case for this function was originally presented by Santosh
Shilimkar <santosh.shilimkar@ti.com>.

Create simple omap_devices for the main processors and busses.
This is required to support the forth-coming device-based OPP
approach, where OPPs are managed and tracked at the device level.
Also, move these common PM init functions into a common_pm_init call
that is called as a device_initcall(). The PM init is done at this level
to ensure that the driver core is initialized before initialized.

On kernels that don't use the omap_device_enable() calls to enable
devices, leave all on-chip devices enabled in hwmod _setup().
Otherwise, accesses to those devices are likely to fail, crashing the
system. It's expected that kernels built without CONFIG_PM_RUNTIME
will be the primary use-case for this. This functionality is
controlled by adding an extra parameter to omap_hwmod_late_init().
This patch is based on the patch "OMAP: hwmod: don't auto-disable
hwmod when !CONFIG_PM_RUNTIME" by Kevin Hilman
<khilman@deeprootsystems.com>.

Some hwmods may need to be idled/enabled in atomic context, so
non-locking versions of these functions are required.
Most users should not need these and usage of theses should be
controlled to understand why access is being done in atomic context.
For this reason, the non-locking functions are only exposed at the
hwmod level and not at the omap-device level.
The use-case that led to the need for the non-locking versions is
hwmods that are enabled/idled from within the core idle/suspend path.
Since interrupts are already disabled here, the mutex-based locking in
hwmod can sleep and will cause potential deadlocks.

AM3505/3517 doesn't have IO wakeup capability, so we do not need to set
the bit OMAP3430_EN_IO and the bit OMAP3430_EN_IO_CHAIN in the register
PM_WKEN_WKUP when the system enters suspend state.
Tested on AM3517EVM and OMAP3530EVM.

Omap DMA controller can prefetch data in advance in case of
destination synchronized data transfer. This may increase
performance when target HW block doesn't have fifo.
Data is waiting for transfer request in DMA fifo instead of read from memory.

Fix GPIO numbers and smc91x for 2430sdp. The earlier code
had cut and paste errors from 3430sdp code. Also, 2430
has five GPIO banks for a total of 160 GPIO lines.

This change adds in the necessary clocks and mux pins for UART
control on omap7xx devices. I also made a change in the serial
code to only try and initialize two UARTs in omap_serial_init, as
these devices don't have three.

Recent DEBUG_LL and uncompress.h changes removed the check_port()
as pointed out by Cory Maccarrone <darkstar6262@gmail.com>.
This causes some boards to not boot, so add back the MDR1 register
check. The MDR1 register tells the mode of omap uart. Based on
an earlier patch by Cory Maccarrone <darkstar6262@gmail.com>.

This patch adds a secure API to read AuxCoreBoot0 register to
check the cpu boot status. It also moves the other smc APIs
to common omap44xx-smc.S. This APIs should not be marked as
__INIT because we need these to be present for CPU hotplug
