* 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.
