+* TSC2005 Touchscreen
+
+Required properties:
+ - compatible		      : "ti,tsc2005"
+ - reg			      : SPI device address
+ - spi-max-frequency	      : Maximal SPI speed
+ - interrupts		      : IRQ specifier
+ - reset-gpio		      : GPIO specifier
+
+Optional properties:
+ - ti,fuzz-x		      : integer, X noise value of the touchscreen
+				(defaults to 4)
+ - ti,fuzz-y		      : integer, Y noise value of the touchscreen
+				(defaults to 8)
+ - ti,fuzz-pressure	      : integer, pressure noise value of the touchscreen
+				(defaults to 2)
+ - ti,max-x		      : integer, maximum reported x value
+				(defaults to 4096)
+ - ti,max-y		      : integer, maximum reported y value
+				(defaults to 4096)
+ - ti,max-pressure	      : integer, maximum reported pressure
+				(defaults to 4096)
+ - ti,x-plate-resistance      : 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.
+
+Example:
+
+&mcspi1 {
+	tsc2005@0 {
+		compatible = "ti,tsc2005";
+		spi-max-frequency = <6000000>;
+		reg = <0>;
+		reset-gpio = <&gpio4 8 GPIO_ACTIVE_HIGH>; /* 104 */
+		interrupt-parent = <&gpio4>;
+		interrupts = <4 IRQ_TYPE_NONE>; /* gpio line 100 */
+
+		ti,fuzz-x = <4>;
+		ti,fuzz-y = <7>;
+		ti,fuzz-pressure = <2>;
+		ti,max-x = <4096>;
+		ti,max-y = <4096>;
+		ti,max-pressure = <2048>;
+		ti,x-plate-resistance = <280>;
+		ti,esd-recovery-timeout-ms = <8000>;
+	};
