I am fine with you removing the runtime PM support in the next
version. I also hope you to upstream the power domain support later
on, that would be nice.

A small note:
>From a driver perspective, you shall be able to implement runtime PM
support even if you haven't upstreamed the power domain support yet.
But, let's then deal with that as a separate patch later on.

Kind regards
