   1TPS6586x family of regulators
   2
   3Required properties:
   4- compatible: "ti,tps6586x"
   5- reg: I2C slave address
   6- interrupts: the interrupt outputs of the controller
   7- #gpio-cells: number of cells to describe a GPIO
   8- gpio-controller: mark the device as a GPIO controller
   9- regulators: A node that houses a sub-node for each regulator within the
  10  device. Each sub-node is identified using the node's name (or the deprecated
  11  regulator-compatible property if present), with valid values listed below.
  12  The content of each sub-node is defined by the standard binding for
  13  regulators; see regulator.txt.
  14  sys, sm[0-2], ldo[0-9] and ldo_rtc
  15- sys-supply: The input supply for SYS.
  16- vin-sm0-supply: The input supply for the SM0.
  17- vin-sm1-supply: The input supply for the SM1.
  18- vin-sm2-supply: The input supply for the SM2.
  19- vinldo01-supply: The input supply for the LDO1 and LDO2
  20- vinldo23-supply: The input supply for the LDO2 and LDO3
  21- vinldo4-supply: The input supply for the LDO4
  22- vinldo678-supply: The input supply for the LDO6, LDO7 and LDO8
  23- vinldo9-supply: The input supply for the LDO9
  24
  25Optional properties:
  26- ti,system-power-controller: Telling whether or not this pmic is controlling
  27  the system power.
  28
  29Each regulator is defined using the standard binding for regulators.
  30
  31Note: LDO5 and LDO_RTC is supplied by SYS regulator internally and driver
  32      take care of making proper parent child relationship.
