|
- compatible : Must be "cortina,gemini-gpio"
|
|
- reg : Should contain registers location and length
|
|
- interrupts : Should contain the interrupt line for the GPIO block
|
|
- gpio-controller : marks this as a GPIO controller
|
|
- #gpio-cells : Should be 2, see gpio/gpio.txt
|
|
- interrupt-controller : marks this as an interrupt controller
|
|
- #interrupt-cells : a standard two-cell interrupt flag, see
|
|
interrupt-controller/interrupts.txt

Example:
|
|
|
|
gpio@4d000000 {
|
|
compatible = "cortina,gemini-gpio";
|
|
reg = <0x4d000000 0x100>;
|
|
interrupts = <22 IRQ_TYPE_LEVEL_HIGH>;
|
|
gpio-controller;
|
|
#gpio-cells = <2>;
|
|
interrupt-controller;
|
|
#interrupt-cells = <2>;
