APM X-Gene SoC GPIO controller bindings |
|
|
|
This is a gpio controller that is part of the flash controller. |
|
This gpio controller controls a total of 48 gpios. |
|
|
|
Required properties: |
|
- compatible: "apm,xgene-gpio" for X-Gene GPIO controller |
|
- reg: Physical base address and size of the controller's registers |
|
- #gpio-cells: Should be two. |
|
- first cell is the pin number |
|
- second cell is used to specify the gpio polarity: |
|
0 = active high |
|
1 = active low |
|
- gpio-controller: Marks the device node as a GPIO controller. |
|
|
|
Example: |
|
gpio0: gpio0@1701c000 { |
|
compatible = "apm,xgene-gpio"; |
|
reg = <0x0 0x1701c000 0x0 0x40>; |
|
gpio-controller; |
|
#gpio-cells = <2>; |
|
};
