This one has a good chance to stick around for a substantial time.

Realistically I see two variants right now:

1) get at least some basics to work (regulators coupling, CPUFreq
voltage managing) and then continue step-by-step

2) give up on it all in upstream because likely that an immediate
complete solution will take just too much time and effort for a one
person to cope (I have other things to do as well)

Mark, I'm glad that you're not strongly opposed. Will prepare v2.

If anyone else has something to say, please don't shy.
