ARM: gpio: consolidate trivial gpiolib implementations
Consolidate 24 trivial gpiolib implementions out of mach/gpio.h into asm/gpio.h. This is basically the include of asm-generic/gpio.h and the definition of gpio_get_value, gpio_set_value, and gpio_cansleep as described in Documentation/gpio.txt Acked-by: H Hartley Sweeten <hsweeten@visionengravers.com> Tested-by: David Brown <davidb@codeaurora.org> Acked-by: David Brown <davidb@codeaurora.org> Tested-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Tested-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
