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

Browse Source 
Pull more input updates from Dmitry Torokhov:
 "An update to the tsc2005 driver that allows it to also support tsc2004
  (basically the same controller, but uses i2c instead of spi bus), and
  a couple of bug fixes"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: parkbd - drop bogus __init from parkbd_allocate_serio()
  Input: elantech - add Fujitsu Lifebook U745 to force crc_enabled
  Input: tsc2004 - add support for tsc2004
  Input: tsc200x-core - rename functions and variables
  Input: tsc2005 - separate SPI and core functions

Required properties:
- compatible : "ti,tsc2005"
- reg : SPI device address
- spi-max-frequency : Maximal SPI speed
- compatible : "ti,tsc2004" or "ti,tsc2005"
- reg : Device address
- interrupts : IRQ specifier
- reset-gpios : GPIO specifier
- vio-supply : Regulator specifier
- spi-max-frequency : Maximum SPI clocking speed of the device
(for tsc2005)
Optional properties:
- vio-supply : Regulator specifier
- reset-gpios : GPIO specifier for the controller reset line
- ti,x-plate-ohms : integer, resistance of the touchscreen's X plates
in ohm (defaults to 280)
- ti,esd-recovery-timeout-ms : integer, if the touchscreen does not respond after
