Ah, yes. We need some kind of this information to know the relation in
the power domain when we wants to power down it.  But it didn't upstream
yet and still in very early stage of the design. I believe you can
ignore that and do the good design here for your usage. We can re-use
the binding if it point to the same HW behind that.

Thanks,
