| 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>; |
| }; |
