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 Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Dong Aisheng <dong.aisheng@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
