Subject: [PATCH 2/3] gpio: Drop asm-generic/gpio.h
Date: Thu,  6 Aug 2015 13:23:51 +0200	[thread overview]
Message-ID: <1438860232-26898-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1438860232-26898-1-git-send-email-s.hauer@pengutronix.de>

Since we no longer have custom gpio function prototypes we can
drop the prototypes from asm-generic/gpio.h can add them to
include/gpio.h instead. While at it add static inline dummy wrappers
for !CONFIG_GENERIC_GPIO so that code using gpios can compile without
gpio support.
