^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) MAX77650 is an ultra-low power PMIC providing battery charging and power
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) supply for low-power IoT and wearable applications.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) The GPIO-controller module is represented as part of the top-level PMIC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) node. The device exposes a single GPIO line.
