Device tree bindings for i2c-cbus-gpio driver
Required properties:
- compatible = "i2c-cbus-gpio";
- gpios: clk, dat, sel
- #address-cells = <1>;
- #size-cells = <0>;
Optional properties:
- child nodes conforming to i2c bus binding
Example:
i2c@0 {
compatible = "i2c-cbus-gpio";
gpios = <&gpio 66 0 /* clk */
&gpio 65 0 /* dat */
&gpio 64 0 /* sel */
>;
#address-cells = <1>;
#size-cells = <0>;
retu-mfd: retu@1 {
compatible = "retu-mfd";
reg = <0x1>;
};
};
