52965cc012 Input: bcm5974 - set BUTTONPAD property
Some bcm5974 trackpads have a physical button beneath the physical surface.
This patch sets the property bit so user space applications can detect the
trackpad type and act accordingly.

4fa0771138 Input: serio_raw - return proper result when serio_raw_write fails
If serio_raw_write was always returning number of bytes successfully
sent to serio port and never signalled error condition to the caller.
Change it so that for completely failed transfers appropriate error
code returned to the caller (partially successful writes still return
number of bytes transferred).

d3d25808df Input: revert some over-zealous conversions to module_platform_driver()
Recent conversion to module_platform_driver() went a bit too far and
converted not only drivers that used platform_driver_register() but
also ones using platform_driver_probe(), breaking them in process.

dfc1ebe766 Device tree conversions for samsung and tegra
Both platforms had some initial device tree support, but this adds
 much more to actually make it usable.
 
 This is where the really nasty conflicts in the samsung platform
 start, due to some files getting moved around and combined in the
 'restart' branch that has already gone into mainline through
 Russell's tree.

73db144b58 Xen: consolidate and simplify struct xenbus_driver instantiation
The 'name', 'owner', and 'mod_name' members are redundant with the
identically named fields in the 'driver' sub-structure. Rather than
switching each instance to specify these fields explicitly, introduce
a macro to simplify this.

Eliminate further redundancy by allowing the drvname argument to
DEFINE_XENBUS_DRIVER() to be blank (in which case the first entry from
the ID table will be used for .driver.name).

Also eliminate the questionable xenbus_register_{back,front}end()
wrappers - their sole remaining purpose was the checking of the
'owner' field, proper setting of which shouldn't be an issue anymore
when the macro gets used.

v2: Restore DRV_NAME for the driver name in xen-pciback.

ee9dfd7a1d Input: psmouse - make sure we do not use stale methods
Several protocol initialization routines can fail after they set up
psmouse methods, such as reconnect and disconnect. This may lead to
these stale methods used with different protocol that they were
intended to be used for and may cause unpredictavle behavior and/or
crashes.

Make sure we start with a clean slate before executing each and every
protocol detection and/or initialization routine.

Without this, it was possible for the reader to get ahead of packet_head.
If the input device generated a partial packet *right* after the reader
got ahead, then we can get into a situation where the device is marked
readable, but read always returns 0 until the next packet is finished
(i.e a SYN is generated by the input driver).

This situation can also happen if we overflow the buffer while a reader
is trying to read an event out.

48c98b1bb8 Input: samsung-keypad - implement runtime power management support
When runtime power management is enabled put the Samsung keypad driver
into suspend mode with wakeups disabled whenever the device is open but
a key is not actually been pressed. As well as saving a trivial amount of
power this will support the use of SoC wide idle modes which put the entire
device into a retention mode and use explicit wakeup sources to exit.

Since not all of the interrupt controllers used with the driver support
set_irq_wake() (though they all do the right thing) and there's a nasty
WARN() when we disable wake after failing to enable it keep track of the
current wake status from runtime PM and only disable wake if we managed
to enable it; I'm not entirely sure why this doesn't affect the existing
uses of the API in the driver.

System suspend is unaffected as the driver core will runtime resume any
suspended devices prior to system suspend.

Some displays from AUO have a so called in-cell touchscreen, meaning it
is built directly into the display unit.

Touchdata is gathered through PIXCIR Tango-ICs and processed in an
Atmel ATmega168P with custom firmware. Communication between the host
system and ATmega is done via I2C.

Devices using this touch solution include the Dell Streak5 and the family
of Qisda ebook readers.

The driver reports single- and multi-touch events including touch area
values.

Make the st1232 driver use dev_pm_qos_add_ancestor_request() to
