pinctrl: add pinctrl_provide_dummies interface for platforms to use
Add a interface pinctrl_provide_dummies for platform to indicate
whether it needs use pinctrl dummy state.
ChangeLog v3->v4:
* remove dummy gpio support in pinctrl subsystem.
Let gpio driver decide whether it wants to use pinctrl gpio mux
function.
ChangeLog v2->v3:
* Also changed the missed pinctrl gpio APIs in v1.
ChangeLog v1->v2:
* Based on sascha's suggestion, drop using kconfig since it will hide
pinctrl errors on all other boards.
See: https://lkml.org/lkml/2012/4/18/282
It seemed both Linus and Stephen agreed with this way, so i'm ok
with it too.
* Add dummy gpio support.
pinctrl gpio in the same situation as state.
* Patch name changed.
Original is pinctrl: handle dummy state in core.
* Split removing old dt dummy interface into a separate patch
