Patch 1/4 has been acked now as well, so I think the remaining part of
this series is ready to go.

However, I noticed that Stephen Rothwell reported some merge conflicts
for arm-soc in linux-next. Quite trivial to resolve, though. Perhaps
an option to consider is to send this as material for v5.10-rc1 (or
maybe rc2) to avoid further conflicts during this release cycle? Just
an idea..

Kind regards
