* 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;
};
};
