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.
