1TI LP873X PMIC MFD driver
2
3Required 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.
