| 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. |
