• 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 : 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@5c {
        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;
    };
};
