 12description: |
 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.
