OK so the first ones we already have so the discussion is now down
to adding the "active" state (and pinctrl_pm* helper function).

I guess we need a patch set prepared which adds the "active" state
and helper function as the first patch, i.e. this:
http://marc.info/?l=linux-kernel&m=137094012703340&w=2
Can I have your ACK on this patch?

I do not want to add the state unless there is a clear consumer,
so it needs to go in with the first patch to a device driver that uses
pinctrl_pm_select_active_state() which will be a good demonstration
on its use and utility. (And a point to object and suggest other ways
to do the same thing...)

Yours,
