| 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. |
