   1 TPS65090 regulators
   2
   3 Required properties:
   4 - compatible: "ti,tps65090"
   5 - reg: I2C slave address
   6 - interrupts: the interrupt outputs of the controller
   7 - regulators: A node that houses a sub-node for each regulator within the
   8   device. Each sub-node is identified using the node's name, with valid
   9   values listed below. The content of each sub-node is defined by the
  10   standard binding for regulators; see regulator.txt.
  11   dcdc[1-3], fet[1-7] and ldo[1-2] respectively.
  12 - vsys[1-3]-supply: The input supply for DCDC[1-3] respectively.
  13 - infet[1-7]-supply: The input supply for FET[1-7] respectively.
  14 - vsys-l[1-2]-supply: The input supply for LDO[1-2] respectively.
  15
  16 Optional properties:
  17 - ti,enable-ext-control: This is applicable for DCDC1, DCDC2 and DCDC3.
  18   If DCDCs are externally controlled then this property should be there.
  19 - "dcdc-ext-control-gpios: This is applicable for DCDC1, DCDC2 and DCDC3.
  20   If DCDCs are externally controlled and if it is from GPIO then GPIO
  21   number should be provided. If it is externally controlled and no GPIO
  22   entry then driver will just configure this rails as external control
  23   and will not provide any enable/disable APIs.
  24
  25 Each regulator is defined using the standard binding for regulators.
