I didn't hear anything and I was sending a new version of the cleanup
patch series, so I:

* Added this last patch to the end of the cleanup series.

* Addressed the "-regulator" suffix issue that Stephen pointed out.

* Didn't remove the SoC compatible from the top-level node in this
patch, but added follow-on patches in the series that do it.

Hopefully that looks good to everyone. I removed both of Stephen's and
Matthias's review tags from the v3 version.
