-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>;
