One thing you haven't called out explicitly here is that this series is
an incompatible change to the DT, since the old buggy driver used to
allow old buggy DT content to accidentally work.

I'm not too familiar with who's using mainline on the Colibri boards.
Hopefully everyone doing that is using in-kernel DTs, so this
incompatible change won't be any issue for anyone.

This patch needs to be rolled into patch 2/3 so that "git bisect" isn't
broken.

You mention there's yet another PMIC version used on later boards. Do we
need a new DT for that specfic version of the Colibri board?
