GPIO driver for MAX77620 Power management IC from Maxim Semiconductor.
Device has 8 GPIO pins which can be configured as GPIO as well as the
special IO functions.
Required properties:
- gpio-controller : Marks the device node as a gpio controller.
- #gpio-cells : Should be two. The first cell is the pin number and
For more details, please refer generic GPIO DT binding documentthe second cell is used to specify the gpio polarity: 0 = active high 1 = active low

Example:
#include <dt-bindings/mfd/max77620.h>
…
max77620@3c {
compatible = “maxim,max77620”;
gpio-controller;
#gpio-cells = <2>;
};
