What would make the common cases easier?

I think from an interface point of view it's something like
UNIVERSAL_DEV_PM_OPS() and friends, probably with some additional ops
that can do the glue bits like enabling wakeup and quiescing activity.
I'd need to think harder about what exactly that'd look like - for my
cases the fundamental thing I want to say is that there's one suspend
routine and one resume routine and I'd like some framework code to work
out when they're called.

Can your device generate wakeup signals?
