    ARM: s3c64xx: get rid of custom <mach/gpio.h> · 41c3548e
    Linus Walleij authored
    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.
