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>; |
|
};
