Well, the bindings should describe what is common for all SoC
and they are quite different in what they need in addition.

In this case it might be possible to add the clock/power-domains
etc. to a wrapper node compatible to "simple-pm-bus" or similar
and make the gpu a child of it.

@Jontahan: can you please give it a try?
