ACT8865 regulator
-------------------
Required properties:
- compatible: "active-semi,act8865"
- reg: I2C slave address
Any standard regulator properties can be used to configure the single regulator.
The valid names for regulators are:
DCDC_REG1, DCDC_REG2, DCDC_REG3, LDO_REG1, LDO_REG2, LDO_REG3, LDO_REG4.
Example:
--------
i2c1: i2c@f0018000 {
pmic: act8865@5b {
compatible = "active-semi,act8865";
reg = <0x5b>;
status = "disabled";
regulators {
vcc_1v8_reg: DCDC_REG1 {
regulator-name = "VCC_1V8";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-always-on;
};
vcc_1v2_reg: DCDC_REG2 {
regulator-name = "VCC_1V2";
regulator-min-microvolt = <1100000>;
regulator-max-microvolt = <1300000>;
regulator-suspend-mem-microvolt = <1150000>;
regulator-suspend-standby-microvolt = <1150000>;
regulator-always-on;
};
vcc_3v3_reg: DCDC_REG3 {
regulator-name = "VCC_3V3";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-always-on;
};
vddana_reg: LDO_REG1 {
regulator-name = "VDDANA";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-always-on;
};
vddfuse_reg: LDO_REG2 {
regulator-name = "FUSE_2V5";
regulator-min-microvolt = <2500000>;
regulator-max-microvolt = <2500000>;
};
};
};
};
