- 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
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
- For more details, please refer generic GPIO DT binding document
- <devicetree/bindings/gpio/gpio.txt>.
- Example:
- --------
- #include <dt-bindings/mfd/max77620.h>
- ...
- max77620@3c {
- compatible = "maxim,max77620";
- gpio-controller;
- #gpio-cells = <2>;
- };
