Ok, so... does the following single node sounds acceptable?

gpio: gpio@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>;
  mediatek,gpio-bank-widths = <32 32 32>;

Why would you need this? It is pretty obvious from the
compatible string isn't it? Just use that to tell that
"aha, it is mediatek,mt7321-gpio, so it has 3x32 GPIOs
indexed from 0..95".

No need of overspecifying stuff.

Ok, So just one node with no extra stuff.

gpio: gpio@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!
