+description: |
+ 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.
