 Replying to [comment:12 dsaxena]:

 > A sysfs one-file-per-bit interface guarantee an atomic update of the
 mask via a read/write lock.

 but how would you guarantee an atomic update of several bits at once?  but
 perhaps that's not necessary in this case.

 fairly trivial; however, I'm wondering if in the long-run it may be better
 to not use sysfs and instead provide a full EC driver of some sort that
 exposes the EC interface to user space to do with it as it pleases.

 that needs to be balanced against possible future platform needs.  as has
 been said, sysfs does make future compatibility more likely, though at
 some cost.
