1* Texas Instruments tsc2004 and tsc2005 touchscreen controllers
2
3Required properties:
4 - compatible		      : "ti,tsc2004" or "ti,tsc2005"
5 - reg			      : Device address
6 - interrupts		      : IRQ specifier
7 - spi-max-frequency	      : Maximum SPI clocking speed of the device
8			        (for tsc2005)
9
10Optional properties:
11 - vio-supply		      : Regulator specifier
12 - reset-gpios		      : GPIO specifier for the controller reset line
13 - ti,x-plate-ohms	      : integer, resistance of the touchscreen's X plates
14				in ohm (defaults to 280)
15 - ti,esd-recovery-timeout-ms : integer, if the touchscreen does not respond after
16				the configured time (in milli seconds), the driver
17				will reset it. This is disabled by default.
