| 12 | description: | |
| 13 | MAX77650 is an ultra-low power PMIC providing battery charging and power |
| 14 | supply for low-power IoT and wearable applications. |
| 15 | |
| 16 | The GPIO-controller module is represented as part of the top-level PMIC |
| 17 | node. The device exposes a single GPIO line. |
| 18 | |
| 19 | For device-tree bindings of other sub-modules (regulator, power supply, |
| 20 | LEDs and onkey) refer to the binding documents under the respective |
| 21 | sub-system directories. |
