-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;
