+* AUO in-cell touchscreen controller using Pixcir sensors
+
+Required properties:
+- compatible: must be "auo,auo_pixcir_ts"
+- 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 {
+		/* ... */
+
+		auo_pixcir_ts@5c {
+			compatible = "auo,auo_pixcir_ts";
+			reg = <0x5c>;
+			interrupts = <2 0>;
+
+			gpios = <&gpf 2 0 2>, /* INT */
+				<&gpf 5 1 0>; /* RST */
+
+			x-size = <800>;
+			y-size = <600>;
+		};
+
+		/* ... */
+	};
