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>;
|
||
|
|
};
