    ARM: s3c24xx: get rid of custom <mach/gpio.h> · c67d0f29
    Linus Walleij authored
    This isolates the custom S3C24xx GPIO definition table to
    <linux/platform_data/gpio-samsung-s3x24xx.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
    We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff.
    The biggest this can ever be for the S3C24XX is
    CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or
    CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512
    is the absolute roof value on this platform. So we set
    the size of ARCH_NR_GPIO to this and the GPIOs array will
    fit any S3C24XX platform, as per pattern from other archs.
    ChangeLog v2->v3:
    - Move the movement of the S3C64XX gpio.h file out of
      this patch and into the follow-up patch where it belongs.
    ChangeLog v1->v2:
    - Added an #ifdef ARCH_S3C24XX around the header inclusion
      in drivers/gpio/gpio-samsung.c as we would otherwise
      have colliding definitions when compiling S3C64XX.
    - Rename inclusion guard in the header file.
