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>;
};
