I just stumbled over pinctrl_pm_select_sleep_state(), is it possible to
integrate this into runtime pm?

http://lxr.free-electrons.com/source/drivers/pinctrl/core.c#L1282

I think those functions are there for the same reason but not sure why aren't
they used in runtime pm core.

Linus W. any hints?

It is not used from PM core because there are cases where
you may want to put pins to sleep for completely PM-core
unrelated things.

Things like turning off a serial port from userspace,
for example. That should put the pins to sleep.
