What I have in mind is - adding the power-controller node with the existing set of power-domains - the gpu pm-domain is in there - adding the gpu parts And a second series with - patch1 from here - a dts patch adding the additional pm-domains to rk3128.dtsi - I guess patch1 also should be split into a patch adding the binding-ids and a separate patch for the code addition.

Right now the existing domain ids in the header are already exposed to the world, so someone could already use them, but not the new ones.

I'm fully aware that nothing would ever hard fail anywhere if the new domain ids get added later. Nevertheless we start using here an ABI which is known to be incomplete. For no reason, as the patches (which I am now asked to remove from this series) for completion are already there (here). Anyway, if you prefer it this way: I'm pleased to do so.

I was more thinking of accelerating the gpu-part of the series, as that really is just waiting for the power-domain node that already has driver support and domain-ids present. It looks like you're feeling more strongly about that though, so I'll definitly not pressure you ;-) . But I guess the split into IDs and driver change should still be done, especially as the dt-binding-header likely will want an Ack from the DT maintainers. And the power-domain change will go through the new pmdomain subsystem.

I'm really not insisting on this - I just didn't understand why you would want this. And honestly I haven't considered merging timeline as an argument. So sure: Let's get the low hanging fruits merged for 6.8. Having the power domains in the DT will also help for my upcoming hdmi / vop series.
