Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device
Required properties:
- compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
Optional properties:
- active-semi,vsel-high: Indicates if the VSEL pin is set to logic-high.
If this property is missing, assume the VSEL pin is set to logic-low.
Optional input supply properties:
- vp1-supply: The input supply for REG_DCDC1
- vp2-supply: The input supply for REG_DCDC2
- vp3-supply: The input supply for REG_DCDC3
- inl45-supply: The input supply for REG_LDO1 and REG_LDO2
- inl67-supply: The input supply for REG_LDO3 and REG_LDO4
Any standard regulator properties can be used to configure the single regulator.
The valid names for regulators are:
REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.
Example:
pmic@5b {
compatible = "active-semi,act8945a";
reg = <0x5b>;
active-semi,vsel-high;
regulators {
vdd_1v35_reg: REG_DCDC1 {
regulator-name = "VDD_1V35";
regulator-min-microvolt = <1350000>;
regulator-max-microvolt = <1350000>;
regulator-always-on;
};
vdd_1v2_reg: REG_DCDC2 {
regulator-name = "VDD_1V2";
regulator-min-microvolt = <1100000>;
regulator-max-microvolt = <1300000>;
regulator-always-on;
};
vdd_3v3_reg: REG_DCDC3 {
regulator-name = "VDD_3V3";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-always-on;
};
vdd_fuse_reg: REG_LDO1 {
regulator-name = "VDD_FUSE";
regulator-min-microvolt = <2500000>;
regulator-max-microvolt = <2500000>;
regulator-always-on;
};
vdd_3v3_lp_reg: REG_LDO2 {
regulator-name = "VDD_3V3_LP";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-always-on;
};
vdd_led_reg: REG_LDO3 {
regulator-name = "VDD_LED";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-always-on;
};
vdd_sdhc_1v8_reg: REG_LDO4 {
regulator-name = "VDD_SDHC_1V8";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-always-on;
};
};
};
