+Atmel maXTouch touchscreen/touchpad
+
+Required properties:
+- compatible:
+    atmel,maxtouch
+
+- reg: The I2C address of the device
+
+- interrupts: The sink for the touchpad's IRQ output
+    See ../interrupt-controller/interrupts.txt
+
+Optional properties for main touchpad device:
+
+- linux,gpio-keymap: An array of up to 4 entries indicating the Linux
+    keycode generated by each GPIO. Linux keycodes are defined in
+    <dt-bindings/input/input.h>.
+
+Example:
+
+	touch@4b {
+		compatible = "atmel,maxtouch";
+		reg = <0x4b>;
+		interrupt-parent = <&gpio>;
+		interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_LOW>;
+	};
