This driver provides support for the RTC part integrated into
the Freescale MC13783 PMIC.
changes since v1:
- use set_mmss instead of set_time
- fix __devinit / __devexit usage
- use platform_driver_probe instead of platform_driver_register
- add MODULE_ALIAS

-Setup pin muxing and register drivers.
-Rename clocks to match new spi driver.
-Change BTN_TOUCH events to ABS_PRESSURE to make tslib happy.

This driver provides support for the touchscreen interface
integrated into the Freescale MC13783.
changes since v1:
- remove unused functions
- use queue_delayed_work instead of queue_work
- report pen events as BTN_TOUCH instead of ABS_PRESSURE
- handle interrupt registration in open/close functions
- do not call input_free_device() on already registered
input_device
- use platform_driver_probe instead of platform_driver_register
- add MODULE_ALIAS

This driver provides the core Freescale MC13783 support. It
registers the client platform_devices and provides access
to the A/D converter.

While there already is a SPI driver for i.MX1 in the tree there are
good reasons to replace it:
- The inkernel driver implements a full blown SPI driver, but
the hardware can be fully supported using a bitbang driver.
This greatly reduces the size and complexity of the driver.
- The inkernel driver only works on i.MX1 SoCs. Unfortunately
Freescale decided to randomly mix the register bits for each
new SoC, This is quite hard to handle with the current driver
since it has register accesses in many places.
- The DMA API of the durrent driver is broken for arch-mx1 (as opposed
to arch-imx) and nobody cared to fix it yet.
This driver has been tested on i.MX1/i.MX27/i.MX35 with an AT25 type
EEPROM and on i.MX27/i.MX31 with a Freescale MC13783 PMIC.

The controller is capable of USB on the go. This patch adds
a driver to support all three of them.
Users have to pass details about serial interface configuration in the
platform data.
The USB OTG core used here is the ARC core, so the driver should
be renamed and probably be merged with ehci-fsl.c eventually.

Andy Whitcroft reported an oops in aoe triggered by use of an
incorrectly initialised request_queue object:
[ 2645.959090] kobject '<NULL>' (ffff880059ca22c0): tried to add
an uninitialized object, something is seriously wrong.
[ 2645.959104] Pid: 6, comm: events/0 Not tainted 2.6.31-5-generic #24-Ubuntu

The request queue of an aoe device is not used but can be allocated in
code that does not sleep.
Bruno bisected this regression down to
cd43e26f071524647e660706b784ebcbefbd2e44
block: Expose stacked device queues in sysfs
"This seems to generate /sys/block/$device/queue and its contents for
everyone who is using queues, not just for those queues that have a
non-NULL queue->request_fn."
Addresses http://bugs.launchpad.net/bugs/410198
Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13942
Note that embedding a queue inside another object has always been
an illegal construct, since the queues are reference counted and
must persist until the last reference is dropped. So aoe was
always buggy in this respect (Jens).

Reinette Chatre reports a frozen system (with blinking keyboard LEDs)
when switching from graphics mode to the text console, or when
suspending (which does the same thing). With netconsole, the oops
turned out to be
BUG: unable to handle kernel NULL pointer dereference at 0000000000000084
IP: [<ffffffffa03ecaab>] i915_driver_irq_handler+0x26b/0xd20 [i915]
and it's due to the i915_gem.c code doing drm_irq_uninstall() after
having done i915_gem_idle(). And the i915_gem_idle() path will do
i915_gem_idle() ->
i915_gem_cleanup_ringbuffer() ->
i915_gem_cleanup_hws() ->
dev_priv->hw_status_page = NULL;
but if an i915 interrupt comes in after this stage, it may want to
access that hw_status_page, and gets the above NULL pointer dereference.
And since the NULL pointer dereference happens from within an interrupt,
and with the screen still in graphics mode, the common end result is
simply a silently hung machine.
Fix it by simply uninstalling the irq handler before idling rather than
after. Fixes

This adds some rv350+ register for LTE/GTE discard,
and enables the rv515 two sided stencil register.
It also disables the DEPTHXY_OFFSET register which
can be used to workaround the CS checker.

- As ima_counts_put() may be called after the inode has been freed,
verify that the inode is not NULL, before dereferencing it.
- Maintain the IMA file counters in may_open() properly, decrementing
any counter increments on subsequent errors.

In ext2_rename(), dir_page is acquired through ext2_dotdot(). It is
then released through ext2_set_link() but only if old_dir != new_dir.
Failing that, the pkmap reference count is never decremented and the
page remains pinned forever. Repeat that a couple times with highmem
pages and all pkmap slots get exhausted, and every further kmap() calls
end up stalling on the pkmap_map_wait queue at which point the whole
system comes to a halt.
