+title: MAX77650 ultra low-power PMIC from Maxim Integrated.
+
+maintainers:
+  - Bartosz Golaszewski <bgolaszewski@baylibre.com>
+
+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.
