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 Cc: Sascha Hauer Acked-by: Stephen Warren Signed-off-by: Dong Aisheng Signed-off-by: Linus Walleij --- include/linux/pinctrl/machine.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'include/linux/pinctrl') diff --git a/include/linux/pinctrl/machine.h b/include/linux/pinctrl/machine.h index 9c4a19867289..7d22ab00343f 100644 --- a/include/linux/pinctrl/machine.h +++ b/include/linux/pinctrl/machine.h @@ -154,7 +154,7 @@ struct pinctrl_map { extern int pinctrl_register_mappings(struct pinctrl_map const *map, unsigned num_maps); - +extern void pinctrl_provide_dummies(void); #else static inline int pinctrl_register_mappings(struct pinctrl_map const *map, @@ -163,5 +163,8 @@ static inline int pinctrl_register_mappings(struct pinctrl_map const *map, return 0; } +static inline void pinctrl_provide_dummies(void) +{ +} #endif /* !CONFIG_PINCTRL */ #endif -- cgit v1.2.2 From c7eea50b980b28f4edaa0cfbdf2456532472bc03 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Wed, 9 May 2012 09:22:40 +0200 Subject: pinctrl: (cosmetic) fix two entries in DocBook comments This removes a repeated word and a repeated and incomplete line from two pinctrl headers.
