Merge branch 'devel-stable' into for-next

Each button (key) is represented as a sub-node of "gpio-keys":

Subnode properties:

	- gpios: OF device-tree gpio specification.

	- interrupts: the interrupt line for that input.

	- label: Descriptive name of the key.

	- linux,code: Keycode to emit.

Required mutual exclusive subnode-properties:

	- gpios: OF device-tree gpio specification.

	- interrupts: the interrupt line for that input

Note that either "interrupts" or "gpios" properties can be omitted, but not

both at the same time. Specifying both properties is allowed.

Optional subnode-properties:

	- linux,input-type: Specify event type this button/key generates.

	- debounce-interval: Debouncing interval time in milliseconds.

	  If not specified defaults to 5.

	- gpio-key,wakeup: Boolean, button can wake-up the system.

	- linux,can-disable: Boolean, indicates that button is connected

	  to dedicated (not shared) interrupt which can be disabled to

	  suppress events from the button.

Example nodes:

 - debounce-interval        : Debouncing interval time in milliseconds

 - st,scan-count            : Scanning cycles elapsed before key data is updated

 - st,no-autorepeat         : If specified device will not autorepeat

 - keypad,num-rows          : See ./matrix-keymap.txt

 - keypad,num-columns       : See ./matrix-keymap.txt

VERSION = 3

PATCHLEVEL = 19

SUBLEVEL = 0

EXTRAVERSION = -rc1

EXTRAVERSION = -rc3
