* 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.
