Hi,

Could someone help to interpret the below device tree structure  in imx6qdl.dtsi?

 

gpio4: gpio@020a8000 {

                compatible = "fsl,imx6q-gpio", "fsl,imx35-gpio";

                reg = <0x020a8000 0x4000>;

                interrupts = <0 72 0x04 0 73 0x04>;

                gpio-controller;

                #gpio-cells = <2>;

                interrupt-controller;

                #interrupt-cells = <2>;

            };

 

my problem is I can not figure out the meaning of "interrupts = <0 72 0x04 0 73 0x04>"
