   1 TPS6586x family of regulators
   2
   3 Required 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: list of regulators provided by this controller, must have
  10   property "regulator-compatible" to match their hardware counterparts:
  11   sm[0-2], ldo[0-9] and ldo_rtc
  12 - vin-sm0-supply: The input supply for the SM0.
  13 - vin-sm1-supply: The input supply for the SM1.
  14 - vin-sm2-supply: The input supply for the SM2.
  15 - vinldo01-supply: The input supply for the LDO1 and LDO2
  16 - vinldo23-supply: The input supply for the LDO2 and LDO3
  17 - vinldo4-supply: The input supply for the LDO4
  18 - vinldo678-supply: The input supply for the LDO6, LDO7 and LDO8
  19 - vinldo9-supply: The input supply for the LDO9
  20
  21 Each regulator is defined using the standard binding for regulators.
