I think you're right that this is a useful and obvious feature but the
question I have is that since the standard implementation is going to be
to do the pinctrl calls in lockstep with the runtime PM handling and
since this is likely to be the same for pretty much any subsystem might
it be better to add the hooks at the runtime PM level rather than in the
subsystem? Or perhaps we should just add them in subsystems and then
once some reasonable number of subsystems have done this then pull it
into the PM core?
Linus, any thoughts?
