I have reviewed the patches, I think they overall looks good! Some
comments though.

You need to split patch 9, the DT parts enabling hw reset shall go in
separately.

Regarding the hw-reset changes in patch1, patch6 and patch9, I believe
I requested you to separate the HW reset changes from $subject
patchset as they are unrelated, please do this.

Running checkpatch, it gave me warnings and errors for patch 8.
Patch7 didn't apply to my next branch.

Kind regards
Uffe
