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