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