Monolithic Power Systems MP8859 voltage regulator
Required properties:
- compatible: "mps,mp8859";
- reg: I2C slave address.
Optional subnode for regulator: "mp8859_dcdc", using common regulator
bindings given in <Documentation/devicetree/bindings/regulator/regulator.txt>.
Example:
mp8859: regulator@66 {
compatible = "mps,mp8859";
reg = <0x66>;
dc_12v: mp8859_dcdc {
regulator-name = "dc_12v";
regulator-min-microvolt = <12000000>;
regulator-max-microvolt = <12000000>;
regulator-boot-on;
regulator-always-on;
};
};
