+* Neonode infrared touchscreen controller
+
+Required properties:
+- compatible: must be "neonode,zforce"
+- reg: I2C address of the chip
+- interrupts: interrupt to which the chip is connected
+- gpios: gpios the chip is connected to
+  first one is the interrupt gpio and second one the reset gpio
+- x-size: horizontal resolution of touchscreen
+- y-size: vertical resolution of touchscreen
+
+Optional properties:
+- vdd-supply: Regulator controlling the controller supply
+
+Example:
+
+       i2c@00000000 {
+               /* ... */
+
+               zforce_ts@50 {
+                       compatible = "neonode,zforce";
+                       reg = <0x50>;
+                       interrupts = <2 0>;
+                       vdd-supply = <&reg_zforce_vdd>;
+
+                       gpios = <&gpio5 6 0>, /* INT */
+                               <&gpio5 9 0>; /* RST */
+
+                       x-size = <800>;
+                       y-size = <600>;
+               };
