So this is the only patch in this series that is still needed.  However...

It doesn't seem like this all by itself is ready for mainline as we'll
suddenly start putting all powerdomains in retention without any
additional support.

I guess at a minimum it needs working IO wakeup support from the IO
daisy chain series.  Are there other dependencies here?

If not, I can queue this when Paul is ready to merge the IO wakeup
stuff.
