It is ~500 and used to be thousands.
An update on that specifically.

Mainline:
$ git grep 'linux\/gpio\.h' | wc -l
505

linux-next:
$ git grep 'linux\/gpio\.h' | wc -l
362

This is because Arnd delete a big slew of unmaintained boardfiles which were
the big offenders.

Now certainly we can fix 362 files soon enough, especially since we have not
just me, but Dmitry T and Andy S and Arnd working on it in parallel.
