Overall this looks great, I had a look through the patches and commented
on the few things that seemed slightly odd though harmless.

Thanks for picking up the subsystem. How do you want to proceed
in the long run? I suppose you can send a pull request to soc@...nel.org
to be picked up for the coming merge window as the normal way, since
you are not yet listed as the maintained until the end of the series.

Afterwards you could either send the pull requests to Linus directly,
or send them to the soc team (or to Greg) as well, the way we handle
a couple of other subsystems like drivers/reset and drivers/tee that
usually only have a handful of patches per release.
