MAX8907 regulator
Required properties:
- compatible: "maxim,max8907"
- reg: I2C slave address
- interrupts: The interrupt output of the controller
- mbatt-supply: The input supply for MBATT, BBAT, SDBY, VRTC.
- in-v1-supply: The input supply for SD1.
- in-v2-supply: The input supply for SD2.
- in-v3-supply: The input supply for SD3.
- in1-supply: The input supply for LDO1.
...
- in20-supply: The input supply for LDO20.
- regulators: A node that houses a sub-node for each regulator within the
device. Each sub-node is identified using the node's name (or the deprecated
regulator-compatible property if present), with valid values listed below.
The content of each sub-node is defined by the standard binding for
regulators; see regulator.txt.
Optional properties:
- maxim,system-power-controller: Boolean property indicating that the PMIC
controls the overall system power.
The valid names for regulators are:
sd1, sd2, sd3, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10,
ldo11, ldo12, ldo13, ldo14, ldo15, ldo16, ldo17, ldo18, ldo19, ldo20, out5v,
out33v, bbat, sdby, vrtc.
Example:
max8907@3c {
compatible = "maxim,max8907";
reg = <0x3c>;
interrupts = <0 86 0x4>;
maxim,system-power-controller;
mbatt-supply = <&some_reg>;
in-v1-supply = <&mbatt_reg>;
...
in1-supply = <&mbatt_reg>;
...
regulators {
mbatt_reg: mbatt {
regulator-name = "vbat_pmu";
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
regulator-always-on;
};
sd1 {
regulator-name = "nvvdd_sv1,vdd_cpu_pmu";
regulator-min-microvolt = <1000000>;
regulator-max-microvolt = <1000000>;
regulator-always-on;
};
sd2 {
regulator-name = "nvvdd_sv2,vdd_core";
regulator-min-microvolt = <1200000>;
regulator-max-microvolt = <1200000>;
regulator-always-on;
};
...
};
};
