+* 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
+
+Example:
+
+ i2c@00000000 {
+ /* ... */
+
+ zforce_ts@50 {
+ compatible = "neonode,zforce";
+ reg = <0x50>;
+ interrupts = <2 0>;
+
+ gpios = <&gpio5 6 0>, /* INT */
+ <&gpio5 9 0>; /* RST */
+
+ x-size = <800>;
+ y-size = <600>;
+ };
+
+ /* ... */
+ };
