hello jake,

here’s an example of interrupt gpio.

        gpio@20 {
                compatible = "nxp,pca9505";
                reg = <0x20>;
                pinctrl-names = "default";
                pinctrl-0 = <&pinctrl_pca9505>;
                interrupt-parent = <&gpio3>;
                interrupts = <23 IRQ_TYPE_LEVEL_LOW>;
        };
