Userspace should do the translation. You should give the user the ability to specify simple, meaningful states, like "on" and "off". But, it should be the tools itself that are mapping those requests to valid input for the sysfs files. Why force the translation into the kernel, and provide more opportunities for error in parsing the sysfs files? Do it in userspace, and you can afford much more flexibility and portability.
