I've a few changes for v6.6, how shall we handle that ?

I think we should continue to use the soc tree until v6.6-rc1 (or if
Arnd have some other ideas), there are some more thoughts around this
in the cover letter.

Beyond v6.6-rc1 I plan to help with maintenance in practice  and run
my own separate git tree.

If it helps I can send you a PR with only the pwrc changes you can merge
before applying this serie.

Right, that could be a good idea, but let's defer to Arnd before we
agree on the way forward.

How about sharing an immutable branch/tag with patch 1, then each one of
us can merge that together with the soc-specific change, followed by any
subsequent patches - leading up to the next merge window.

Stephen will have a merge conflict in drivers/genpd/Makefile as each
soc-specific addition comes in, and Arnd will see this conflict too. But
this is going to be extremely trivial. But apart from this, there will
not be any conflicts or additional branching constraints for us...

Regards,
Bjorn

Kind regards
Uffe
