Looks good. Only too imo minor things:
- Drop the runtime pm get/put from the forcewake get/put functions and
  adjust callers accordingly to grab the runtime pm ref themselves outside
  of the register access. That should fully address Chris'&mine concern in
  that regard. I only expect a minor impact here, if that turns out wrong
  please complain and we need to take another look.

- The aux display power domain patch. Needs acks from platform owners imo,
  I'd just keep it for now.

Also I've merged quite a few patches already, hopefully the most recent
versions. When rebasing pls collect all the r-b tags for speedy merging.

Thanks, Daniel
