It uses the default two cells specifier as described in Documentation/devicetree/bindings/ interrupt-controller/interrupts.txt. Example: gpio_0: gpio_mediam@17040000 { compatible = "sirf,atlas7-gpio"; reg = <0x17040000 0x1000>; interrupts = <0 13 0>, <0 14 0>; #gpio-cells = <2>; #interrupt-cells = <2>; gpio-controller; interrupt-controller; gpio-banks = <2>; gpio-ranges = <&pinctrl 0 0 0>, <&pinctrl 32 0 0>; gpio-ranges-group-names = "lvds_gpio_grp", "uart_nand_gpio_grp"; }; leds { compatible = "gpio-leds"; led1 { gpios = <&gpio_1 15 0>; ... }; led2 { gpios = <&gpio_2 34 0>; ... }; }; Please refer to gpio.txt in this directory for details of the common gpio properties used by devices. |
