* 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.
 - properties defined in touchscreen.txt

Example:

&i2c3 {
	tsc2004@48 {
		compatible = "ti,tsc2004";
		reg = <0x48>;
		vio-supply = <&vio>;

reset-gpios = <&gpio4 8 GPIO_ACTIVE_HIGH>;
		interrupts-extended = <&gpio1 27 IRQ_TYPE_EDGE_RISING>;

touchscreen-fuzz-x = <4>;
		touchscreen-fuzz-y = <7>;
		touchscreen-fuzz-pressure = <2>;
		touchscreen-size-x = <4096>;
		touchscreen-size-y = <4096>;
		touchscreen-max-pressure = <2048>;

ti,x-plate-ohms = <280>;
		ti,esd-recovery-timeout-ms = <8000>;
	};
}

&mcspi1 {
	tsc2005@0 {
		compatible = "ti,tsc2005";
		spi-max-frequency = <6000000>;
		reg = <0>;

vio-supply = <&vio>;

reset-gpios = <&gpio4 8 GPIO_ACTIVE_HIGH>; /* 104 */
		interrupts-extended = <&gpio4 4 IRQ_TYPE_EDGE_RISING>; /* 100 */

touchscreen-fuzz-x = <4>;
		touchscreen-fuzz-y = <7>;
		touchscreen-fuzz-pressure = <2>;
		touchscreen-size-x = <4096>;
		touchscreen-size-y = <4096>;
		touchscreen-max-pressure = <2048>;

ti,x-plate-ohms = <280>;
		ti,esd-recovery-timeout-ms = <8000>;
	};
}
