Monolithic Power Systems MP8867/MP8869 voltage regulator



Required properties:

- compatible: Must be one of the following.

	"mps,mp8867"

	"mps,mp8869"

- reg: I2C slave address.

- enable-gpios: enable gpios.

- mps,fb-voltage-divider: An array of two integers containing the resistor

  values R1 and R2 of the feedback voltage divider in kilo ohms.



Optional properties:

- mps,switch-frequency-hz: The valid switch frequency in Hertz. Available values

  are: 500000, 750000, 1000000, 1250000, 1500000



Any property defined as part of the core regulator binding, defined in

./regulator.txt, can also be used.



Example:



	vcpu: regulator@62 {

		compatible = "mps,mp8869";

		regulator-name = "vcpu";

		regulator-min-microvolt = <700000>;

		regulator-max-microvolt = <850000>;

		regulator-always-on;

		regulator-boot-on;

		enable-gpios = <&porta 1 GPIO_ACTIVE_LOW>;

		mps,fb-voltage-divider = <80 240>;

		reg = <0x62>;

	};
