- 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>;
- };
