+GPIO driver for MAX77650 PMIC from Maxim Integrated.
+
+This module is part of the MAX77650 MFD device. For more details
+see Documentation/devicetree/bindings/mfd/max77650.txt.
+
+The GPIO controller is represented as a sub-node of the PMIC node on
+the device tree.
+
+This device has a single GPIO pin.
+
+Required properties:
+--------------------
+- compatible: Must be "maxim,max77650-gpio"
+- gpio-controller : Marks the device node as a gpio controller.
+- #gpio-cells : Must be <2>. The first cell is the pin number and
+ the second cell is used to specify the gpio active
+ state.
+
+Optional properties:
+--------------------
+gpio-line-names: Single string containing the name of the GPIO line.
+
+For more details, please refer to the generic GPIO DT binding document
+<devicetree/bindings/gpio/gpio.txt>.
+
+Example:
+--------
+
+ gpio {
+ compatible = "maxim,max77650-gpio";
+ gpio-line-names = "max77650-charger";
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
