I think that there is a mistake in that patch #power-domain-cells =
<1>; should not be removed. Anyway, I talked with Matthias and I'm
going to redefine this part as doesn't really match with the hardware.
We're thinking on something like this:

scpsys: syscon@10006000 {
     compatible = "mediatek,mtk-scpsys", "syscon";
      reg = ...

     power-controller {
           compatible = "mediatek,mt8173-power-controller";
           #power-domain-cells = <1>;

           <- the list of domains ->

Thanks,
  Enric
