This is a part of device tree bindings for Maxim MAX77802 Power Management
|
||
|
|
Integrated Circuit (PMIC).
|
||
|
|
|
||
|
|
The Maxim MAX77802 is a Power Management IC which includes voltage and
|
||
|
|
current regulators (10 high efficiency Buck regulators and 32 Low-DropOut
|
||
|
|
(LDO)), RTC and clock outputs.
|
||
|
|
|
||
|
|
The MAX77802 provides two 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,max77802.h.
