Hm so I have had this idea of runtime PM core helping out
with pins, so I could add something like
So if one is using the pin states defined in <linux/pinctrl/pinctrl-state.h>
then the PM core can help out in keeping track of the pins
and states, and the driver will just tell the PM core what
to do and when.
Would this fit the bill for everyone's code consolidation needs?
It would sure work for us...
It however require that no custom states are used and that we
keep to the state semantics I just happen to think is most
