* Texas Instruments tsc2004 and tsc2005 touchscreen controllers

	Required properties:
	 - compatible		      : "ti,tsc2004" or "ti,tsc2005"
	 - reg			      : Device address
	 - interrupts		      : IRQ 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
					the configured time (in milli
seconds), the driver
					will reset it. This is disabled by
default.
