Works for me. Do you intend to apply it directly? Otherwise I'll
add on my tree - and likely send you during the merge window - this is
just Kconfig random COMPILE_TEST build noise, as this driver
is ARM-only (for an OMAP4 specific IP block). So, probably not worth
sending a pull request just due to that.

Yeah, some time ago mailing lists got flooded with some janitorial's
patchset adding includes (some claiming to be needed on some archs or
under some random Kconfigs)... Compile-test ended by adding more such
stuff (for a good reason, IMHO). I wonder if are there a better way to
handle includes without slowing builds.

Thanks,
Mauro
