[For future reference, if you're going to CC me on most of a patch series,
I'd really rather get the whole thing so I don't have to go looking for
it.]

wonder if sysfs.txt should just be removed, since it documents something
we don't want people to use at this point?  Historical purposes are well
served by the repository history.

I'd say changing the headings is worthwhile if it produces a better
result.  OTOH I'd be wary of adding too much "polish"; we really want to
retain the readability of the plain-text files.

Anyway, I'm happy to take these through the docs tree or see them go via
GPIO; Linus, what's your preference?

Thanks,
