Hrm, this is the first I'd noticed that feature though I see the initial
commit dates from January. It looks like most of the users are PCs at
the minute but we should be using it more widely for embedded things,
there's definitely some cases I'm aware of where it will allow us to
remove some open coding.
It does seem like we want to be feeding dependency information we
discover for probing way into the suspend dependencies...
