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

Pull input updates from Dmitry Torokhov:
 "A tiny pull request this merge window unfortunately, should get more
  material in for the next release:

   - new driver for Raspberry Pi's touchscreen (firmware interface)

   - miscellaneous input driver fixes"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: elan_i2c - add ACPI ID for touchpad in ASUS Aspire F5-573G
  Input: atmel_mxt_ts - don't try to free unallocated kernel memory
  Input: drv2667 - fix indentation issues
  Input: touchscreen - fix coding style issue
  Input: add official Raspberry Pi's touchscreen driver
  Input: nomadik-ske-keypad - fix a loop timeout test
  Input: rotary-encoder - don't log EPROBE_DEFER to kernel log
  Input: olpc_apsp - remove set but not used variable 'np'
  Input: olpc_apsp - enable the SP clock
  Input: olpc_apsp - check FIFO status on open(), not probe()
  Input: olpc_apsp - drop CONFIG_OLPC dependency
  clk: mmp2: add SP clock

Raspberry Pi firmware based 7" touchscreen

=====================================



Required properties:

 - compatible: "raspberrypi,firmware-ts"



Optional properties:

 - firmware: Reference to RPi's firmware device node

 - touchscreen-size-x: See touchscreen.txt

 - touchscreen-size-y: See touchscreen.txt

 - touchscreen-inverted-x: See touchscreen.txt

 - touchscreen-inverted-y: See touchscreen.txt

 - touchscreen-swapped-x-y: See touchscreen.txt



Example:



firmware: firmware-rpi {

	compatible = "raspberrypi,bcm2835-firmware";

	mboxes = <&mailbox>;



	ts: touchscreen {

		compatible = "raspberrypi,firmware-ts";

		touchscreen-size-x = <800>;
