I took a rough look at the entire series and only have a few
minor comments to one patch, otherwise it looks fine to me.

I would still prefer for Li Yang to merge the patches and
send the pull request to soc@...nel.org, but if this also
gets stalled because of lack of feedback and there are no
objections to the content, you can send a PR there yourself.
