0012 description: |
0013 MAX77650 is an ultra-low power PMIC providing battery charging and power
0014 supply for low-power IoT and wearable applications.
0015
0016 The GPIO-controller module is represented as part of the top-level PMIC
0017 node. The device exposes a single GPIO line.
0018
0019 For device-tree bindings of other sub-modules (regulator, power supply,
0020 LEDs and onkey) refer to the binding documents under the respective
0021 sub-system directories.
