Ok, So just one node with no extra stuff.

gpio: gpio at 600 {
   #gpio-cells = <2>;
   #interrupt-cells = <2>;
   compatible = "mediatek,mt7621-gpio";
   gpio-controller;
   interrupt-controller;
   reg = <0x600 0x60>;
   interrupt-parent = <&gic>;
   interrupts = <GIC_SHARED 12 IRQ_TYPE_LEVEL_HIGH>;

Thanks for your answers!
