A couple of remarks either for the next version of the series or for
the follow ups.

I'm wondering why OF.
If it's a functional dependency (I do not see compile-time one) the
compile test can be added, no?

  depends on GPIOLIB
  depends on OF || COMPILE_TEST

There is a wrong header (the code doesn't use this one).
You meant mod_devicetable.h

Besides that kernel.h for ARRAY_SIZE() init.h for arch_initcall() and
others might be missing.
