Kernel-3.10.0-957.el7_max8907

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;
            };
