+* Texas Instruments tsc2005 touchscreen controller
+
+Required properties:
+ - compatible : "ti,tsc2005"
+ - reg : SPI device address
+ - spi-max-frequency : Maximal SPI speed
+ - interrupts : IRQ specifier
+ - reset-gpios : GPIO specifier
+ - vio-supply : Regulator specifier
+
+Optional properties:
+ - 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:
+
+&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-max-x = <4096>;
+ touchscreen-max-y = <4096>;
+ touchscreen-max-pressure = <2048>;
+
+ ti,x-plate-ohms = <280>;
+ ti,esd-recovery-timeout-ms = <8000>;
+ };
