Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Browse Source 
Pull input layer updates from Dmitry Torokhov:
 - a bunch of new drivers (DA9052/53 touchscreenn controller, Synaptics
   Navpoint, LM8333 keypads, Wacom I2C touhscreen);
 - updates to existing touchpad drivers (ALPS, Sntelic);
 - Wacom driver now supports Intuos5;
 - device-tree bindings in numerous drivers;
 - other cleanups and fixes.

Fix annoying conflict in drivers/input/tablet/wacom_wac.c that I think
implies that the input layer device naming is broken, but let's see.  I
brough it up with Dmitry.

tristate "Synaptics NavPoint (PXA27x SSP/SPI)"
depends on PXA27x && PXA_SSP
help
This driver adds support for the Synaptics NavPoint touchpad connected
to a PXA27x SSP port in SPI slave mode. The device emulates a mouse;
a tap or tap-and-a-half drag gesture emulates the left mouse button.
For example, use the xf86-input-evdev driver for an X pointing device.
To compile this driver as a module, choose M here: the
module will be called navpoint.
