2014-06-30ARM: delete old reference to ARM_GPIOLIB_COMPLEXLinus Walleij
This inclusion guard became pointless after commit 40ca061b1bb8827609d39679ddde6705551cb031 "ARM: 7841/1: sa1100: remove complex GPIO interface" which removed the last complex gpiolib interface.

2014-06-30ARM: kill CONFIG_NEED_MACH_GPIO_HLinus Walleij
The long pain of maintaining the legacy <mach/gpio.h> include ladder is now gone with S5P as the last user being deleted. Cut this Kconfig option and remove the inclusion directive in <asm/gpio.h> for good. Acked-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-09-14ARM: make mach/gpio.h headers optionalRob Herring
Most platforms don't need mach/gpio.h and it prevents multi-platform kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX or have lots of implicit includes pulled in by mach/gpio.h. at91 and omap have gpio clean-up pending and can drop CONFIG_NEED_MACH_GPIO_H once that is in.

2012-01-08ARM: 7271/1: Fix typo in conversion of ARCH_NR_GPIOS to KconfigStephen Warren
Commit 44986ab "ARM: 7240/1: Make ARCH_NR_GPIO a Kconfig variable" spelled ARCH_NR_GPIOS as ARCH_NR_GPIO, hence making the change ineffective. This change fixes that. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-12-23ARM: 7240/1: Make ARCH_NR_GPIO a Kconfig variablePeter De Schrijver (NVIDIA)
Change ARCH_NR_GPIO into a Kconfig variable as suggested by Russel King. This makes ARCH_NR_GPIO single zImage friendly. The default value for tegra is defined as well. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-08-12ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King
Rather than marking the mach/gpio.h header files which want to use the trivial GPIOLIB implementation, mark those which do not want to use it instead. This means that by default, you get the trivial implementation and only have to do something extra if you need to. This should encourage the use of the trivial default implementation. As an additional bonus, several gpio.h header files become empty.

2011-08-12ARM: gpio: consolidate gpio_to_irqRussell King
Many of the gpio_to_irq implementations use the gpiolib version of this function. Provide the standard gpiolib gpio_to_irq() for everyone, but allow platforms to override it if they wish. Add the neccessary overrides for those platforms which do not use the standard definition. Acked-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-08-12ARM: gpio: consolidate trivial gpiolib implementationsRussell King
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>
2008-08-07[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King
This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-08-02[ARM] move include/asm-arm to arch/arm/include/asmRussell King
Move platform independent header files to arch/arm/include/asm, leaving those in asm/arch* and asm/plat* alone. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
