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

Pull input updates from Dmitry Torokhov:
 "Two new touchpad drivers - Cypress APA I2C Trackpad and Cypress PS/2
  touchpad and a big update to ALPS driver from Kevin Cernekee that adds
  support for "Rushmore" touchpads and paves way for adding support for
  "Dolphin" touchpads.

  There is also a new input driver for Goldfish emulator and also
  Android keyreset driver was folded into SysRq code.

  A few more drivers were updated with device tree bindings and others
  got some small cleanups and fixes."

+* Freescale i.MX Keypad Port(KPP) device tree bindings
+
+The KPP is designed to interface with a keypad matrix with 2-point contact
+or 3-point contact keys. The KPP is designed to simplify the software task
+of scanning a keypad matrix. The KPP is capable of detecting, debouncing,
+and decoding one or multiple keys pressed simultaneously on a keypad.
+
+Required SoC Specific Properties:
+- compatible: Should be "fsl,<soc>-kpp".
+
+- reg: Physical base address of the KPP and length of memory mapped
+  region.
+
+- interrupts: The KPP interrupt number to the CPU(s).
+
+- clocks: The clock provided by the SoC to the KPP. Some SoCs use dummy
+clock(The clock for the KPP is provided by the SoCs automatically).
