Hello!
Can I get pin status of GPIO ? Probably, the function s3c2410_gpio_getpin() not return pin status...

Just checking ... are you aware of the unique way the ports are named in Linux? I can only give you the search terms avrfreaks sysfs gpio. Also there are probably only a few pins enabled
in the kernel driver. See mach-mini2440.c
Good luck
