   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: 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
  25 Each regulator is defined using the standard binding for regulators.
  26
  27 Note: LDO5 and LDO_RTC is supplied by SYS regulator internally and driver
  28       take care of making proper parent child relationship.
