+* Microchip AR1020 and AR1021 touchscreen interface (I2C)
+
+Required properties:
+- compatible : use "microchip,ar1020-i2c" or "microchip,ar1021-i2c"
+- reg : I2C slave address
+- interrupt-parent : the phandle for the interrupt controller
+- interrupts : touch controller interrupt
+
+Example:
+
+ ar1020: ar1020@4d {
+ compatible = "microchip,ar1020-i2c";
+ reg = <0x4d>;
+ interrupt-parent = <&gpio3>;
+ interrupts = <11 IRQ_TYPE_LEVEL_HIGH>;
