Maxim MAX77693 multi-function device
|
||
|
|
|
||
|
|
MAX77693 is a Multifunction device with the following submodules:
|
||
|
|
- PMIC,
|
||
|
|
- CHARGER,
|
||
|
|
- LED,
|
||
|
|
- MUIC,
|
||
|
|
- HAPTIC
|
||
|
|
|
||
|
|
It is interfaced to host controller using i2c.
|
||
|
|
This document describes the bindings for the mfd device.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : Must be "maxim,max77693".
|
||
|
|
- reg : Specifies the i2c slave address of PMIC block.
|
||
|
|
- interrupts : This i2c device has an IRQ line connected to the main SoC.
|
||
|
|
- interrupt-parent : The parent interrupt controller.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- regulators : The regulators of max77693 have to be instantiated under subnod
|
||
|
|
named "regulators" using the following format.
|
||
|
|
|
||
|
|
regulators {
