   2
   3 Required properties:
   4 - compatible: "maxim,max8907"
   5 - reg: I2C slave address
   6 - interrupts: The interrupt output of the controller
   7 - mbatt-supply: The input supply for MBATT, BBAT, SDBY, VRTC.
   8 - in-v1-supply: The input supply for SD1.
   9 - in-v2-supply: The input supply for SD2.
  10 - in-v3-supply: The input supply for SD3.
  11 - in1-supply: The input supply for LDO1.
  12 ...
  13 - in20-supply: The input supply for LDO20.
  14 - regulators: A node that houses a sub-node for each regulator within the
  15   device. Each sub-node is identified using the node's name (or the deprecated
  16   regulator-compatible property if present), with valid values listed below.
  17   The content of each sub-node is defined by the standard binding for
  18   regulators; see regulator.txt.

  20 Optional properties:
  21 - maxim,system-power-controller: Boolean property indicating that the PMIC
  22   controls the overall system power.
  23
  24 The valid names for regulators are:
  25
  26   sd1, sd2, sd3, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10,
  27   ldo11, ldo12, ldo13, ldo14, ldo15, ldo16, ldo17, ldo18, ldo19, ldo20, out5v,
  28   out33v, bbat, sdby, vrtc.
