-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>;
- };
