ARM: S5PC100: GPIO and I2C
S5PC100 has more GPIO group then previous one. It has 34 groups of GPIO, while S3C6410 has 17 groups. For now, only header files are written. Signed-off-by: Byungho Min <bhmin@samsung.com> [ben-linux@fluff.org: subject fixup] Signed-off-by: Ben Dooks <ben-linux@fluff.org>
