   1 TI LP873X PMIC MFD driver
   2
   3 Required properties:
   4   - compatible: "ti,lp8732", "ti,lp8733"
   5   - reg:                I2C slave address.
   6   - gpio-controller:    Marks the device node as a GPIO Controller.
   7   - #gpio-cells:        Should be two.  The first cell is the pin number and
   8                         the second cell is used to specify flags.
   9                         See ../gpio/gpio.txt for more information.
  10   - xxx-in-supply:      Phandle to parent supply node of each regulator
  11                         populated under regulators node. xxx can be
  12                         buck0, buck1, ldo0 or ldo1.
  13   - regulators: List of child nodes that specify the regulator
  14                         initialization data.
