* ARM: s3c64xx: get rid of custom <mach/gpio.h>Linus Walleij2013-12-201-93/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | This isolates the custom S3C64xx GPIO definition table to <linux/platform_data/gpio-samsung-s3x64xx.h> as this is used in a few different places in the kernel, removing the need to depend on the implicit inclusion of <mach/gpio.h> from <linux/gpio.h> and thus getting rid of a few nasty cross-dependencies. Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead roof the number of GPIOs for this platform: First sum up all the GPIO banks from A to Q: 187 GPIOs. Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA, 128, so in total maximum 187+16+128 = 331 GPIOs, so let's take the same roof as for S3C24XX: 512. This way we can do away with the GPIO calculation macros for GPIO_BOARD_START, BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.

* ARM: S3C64XX: Update for conversion to SAMSUNG_GPIO_EXTRAMark Brown2011-11-081-1/+1
| | | | | | | | | | | | | The conversion of the S3C64XX GPIOs to the generic Samsung GPIOs mean that rather than using the previous S3C24XX_GPIO_EXTRA configuration the driver now uses SAMSUNG_GPIO_EXTRA. Since SAMSUNG_GPIO_EXTRA requires the arch to include the extra space in ARCH_NR_GPIOs add it on to BOARD_NR_GPIOs (in case boards are relying on the existing reservation).

* ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King2011-08-121-2/+0
| | | | | | | | | | | | | | | 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 King2011-08-121-1/+0
| | | | | | | | | | 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 King2011-08-121-5/+1
| | | | | | | | | | | | | | | 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: S3C64XX: Merge mach-s3c6400 and mach-s3c6410Ben Dooks2010-01-261-0/+96
As per discussions with Russell King on linux-arm-kernel, it appears that both mach-s3c6400 and mach-s3c6410 are so close together that they should simply be merged into mach-s3c64xx. Note, this patch does not eliminate any of the bits that are still common, it is simply a move of the two directories together, any further common code will be eliminated or moved in further patches.
