* ARM: make mach/gpio.h headers optionalRob Herring2012-09-141-0/+2
| | | | | | | | | | | | | | | 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.

* ARM: 7271/1: Fix typo in conversion of ARCH_NR_GPIOS to KconfigStephen Warren2012-01-081-1/+1
| | | | | | | | | 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>
* ARM: 7240/1: Make ARCH_NR_GPIO a Kconfig variablePeter De Schrijver (NVIDIA)2011-12-231-0/+4
| | | | | | | | | 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.

* ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King2011-08-121-1/+1
| | | | | | | | | | | | | | | 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.

* ARM: gpio: consolidate gpio_to_irqRussell King2011-08-121-0/+9
| | | | | | | | | | 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.

* ARM: gpio: consolidate trivial gpiolib implementationsRussell King2011-08-121-0/+10
| | | | | | | | | | | | | | | 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>

* [ARM] move include/asm-arm to arch/arm/include/asmRussell King2008-08-021-0/+7
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>
