Usually I pick up the power-domain related changes for the DT bindings
and host them via an immutable branch called "dt". If needed, SOC
maintainers can pull it to apply/test the corresponding DTS changes.

That said, I am open to whatever you think is best here. Perhaps it's
easier if you can drop the DT patches and provide your acks instead or
if you can share them via an immutable branch for me to pull?

Kind regards
Uffe
