Well, it would be actually nice for you to do the cherry
picking. That's something maintainers do, because it is hard for
contributors to guess maintainer's taste.

Anyway, it looks like someone should go through all the RTC drivers,
and document their limitations of each driver (date in future when
hardware ceases to be useful). If Benjamin has time to do that, I
guess that removes all the objections to the series.
