| 14 | This is a part of device tree bindings for Maxim MAX77802 Power Management |
| 15 | Integrated Circuit (PMIC). |
| 16 | |
| 17 | The Maxim MAX77802 is a Power Management IC which includes voltage and |
| 18 | current regulators (10 high efficiency Buck regulators and 32 Low-DropOut |
| 19 | (LDO)), RTC and clock outputs. |
| 20 | |
| 21 | The MAX77802 provides two 32.768khz clock outputs that can be controlled |
| 22 | (gated/ungated) over I2C. The clock IDs are defined as preprocessor macros |
| 23 | in dt-bindings/clock/maxim,max77802.h. |
