+* Rohm BU21013 Touch Screen
+
+Required properties:
+ - compatible : "rohm,bu21013_tp"
+ - reg : I2C device address
+
+Optional properties:
+ - touch-gpio : GPIO pin registering a touch event
+ - <supply_name>-supply : Phandle to a regulator supply
+ - rohm,touch-max-x : Maximum outward permitted limit in the X axis
+ - rohm,touch-max-y : Maximum outward permitted limit in the Y axis
+ - rohm,flip-x : Flip touch coordinates on the X axis
+ - rohm,flip-y : Flip touch coordinates on the Y axis
+
+Example:
+
+ i2c@80110000 {
+ bu21013_tp@0x5c {
+ compatible = "rohm,bu21013_tp";
+ reg = <0x5c>;
+ touch-gpio = <&gpio2 20 0x4>;
+ avdd-supply = <&ab8500_ldo_aux1_reg>;
+
+ rohm,touch-max-x = <384>;
+ rohm,touch-max-y = <704>;
+ rohm,flip-y;
+ };
+ };
