When refactoring and breaking out the includes for the machine-specific GPIO configuration, two files were created in <linux/platform_data/gpio-samsung-s3c[24|64]xx.h>, but as that namespace shall be used for defining data exchanged between machines and drivers, using it for these broad macros and config settings is wrong. Move the headers back into the machine-local <mach/gpio-samsung.h> file and think about the next step.
