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

…/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - three new touchscreen drivers: EETI EXC3000, HiDeep, and Samsung
   S6SY761

 - the timer API conversion (setup_timer() -> timer_setup())

 - a few drivers swiytched to using managed API for creating custom
   device attributes

 - other assorted fixed and cleanups.

+This simply uses standard GPIO handles to define a simple mouse connected
+to 5-7 GPIO lines.

+	- up-gpios: GPIO line phandle to the line indicating "up"
+	- down-gpios: GPIO line phandle to the line indicating "down"
