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

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.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (57 commits)
  Input: matrix-keymap - fix building keymaps
  Input: spear-keyboard - document DT bindings
  Input: spear-keyboard - add device tree bindings
  Input: matrix-keymap - wire up device tree support
  Input: matrix-keymap - uninline and prepare for device tree support
