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

Pull input updates from Dmitry Torokhov:
 "First round of updates for the input subsystem.

  You will get a new touchsreen driver for Cypress 4th generation
  devices, a driver for a special controller implementing PS/2 protocol
  in OLPC devices, and a driver for power key for SiRFprimaII PWRC.

  HID and bcm5497 now support for the 2013 MacBook Air.

  EVIOCGKEY and the rest of evdev ioctls now flush events of matching
  type from the client's event queue so that clients can be sure any
  events received after issuing EVIOCG* ioctl are new events.

  And a host of cleanups and improvements in other drivers"

+* Marvell PXA Keypad controller
+
+Required Properties
+- compatible : should be "marvell,pxa27x-keypad"
+- reg : Address and length of the register set for the device
+- interrupts : The interrupt for the keypad controller
+- marvell,debounce-interval : How long time the key will be
+  recognized when it is pressed. It is a u32 value, and bit[31:16]
+  is debounce interval for direct key and bit[15:0] is debounce
+  interval for matrix key. The value is in binary number of 2ms
+
+Optional Properties For Matrix Keyes
+Please refer to matrix-keymap.txt
+
+Optional Properties for Direct Keyes
+- marvell,direct-key-count : How many direct keyes are used.
+- marvell,direct-key-mask : The mask indicates which keyes
+  are used. If bit[X] of the mask is set, the direct key X
+  is used.
+- marvell,direct-key-low-active : Direct key status register
+  tells the level of pins that connects to the direct keyes.
+  When this property is set, it means that when the pin level
+  is low, the key is pressed(active).
+- marvell,direct-key-map : It is a u16 array. Each item indicates
+  the linux key-code for the direct key.
+
+Optional Properties For Rotary
+- marvell,rotary0 : It is a u32 value. Bit[31:16] is the
+  linux key-code for rotary up. Bit[15:0] is the linux key-code
+  for rotary down. It is for rotary 0.
+- marvell,rotary1 : Same as marvell,rotary0. It is for rotary 1.
+- marvell,rotary-rel-key : When rotary is used for relative axes
+  in the device, the value indicates the key-code for relative
+  axes measurement in the device. It is a u32 value. Bit[31:16]
+  is for rotary 1, and Bit[15:0] is for rotary 0.
