This is a part of device tree bindings for Maxim MAX77686 Power Management
|
|
Integrated Circuit (PMIC).
|
|
|
|
The Maxim MAX77686 is a Power Management IC which includes voltage and
|
|
current regulators, RTC and clock outputs.
|
|
|
|
The MAX77686 provides three 32.768khz clock outputs that can be controlled
|
|
(gated/ungated) over I2C. The clock IDs are defined as preprocessor macros
|
|
in dt-bindings/clock/maxim,max77686.h.
