* Powerventure Semiconductor PV88080 Voltage Regulator
Required properties:
- compatible: "pvs,pv88080".
- reg: I2C slave address, usually 0x49.
- interrupts: the interrupt outputs of the controller
- regulators: A node that houses a sub-node for each regulator within the
device. Each sub-node is identified using the node's name, with valid
values listed below. The content of each sub-node is defined by the
standard binding for regulators; see regulator.txt.
BUCK1, BUCK2, and BUCK3.
Optional properties:
- Any optional property defined in regulator.txt
Example
pmic: pv88080@49 {
compatible = "pvs,pv88080";
reg = <0x49>;
interrupt-parent = <&gpio>;
interrupts = <24 24>;
regulators {
BUCK1 {
regulator-name = "buck1";
regulator-min-microvolt = < 600000>;
regulator-max-microvolt = <1393750>;
regulator-min-microamp = < 220000>;
regulator-max-microamp = <7040000>;
};
BUCK2 {
regulator-name = "buck2";
regulator-min-microvolt = < 600000>;
regulator-max-microvolt = <1393750>;
regulator-min-microamp = <1496000>;
regulator-max-microamp = <4189000>;
};
BUCK3 {
regulator-name = "buck3";
regulator-min-microvolt = <1400000>;
regulator-max-microvolt = <2193750>;
regulator-min-microamp = <1496000>;
regulator-max-microamp = <4189000>;
