Why do you say that?

Which option do you mean?

My BBB is running the GENERIC kernel configuration, I have a device tree 
overlay to get the dtmpps driver to attach and a patch to fix a problem with 
the PPS timehands capture (which is now committed).

I checked the source and the header plus parallel port implementation was 
committed over 20 years ago, the serial capture was over 15 years ago and the 
dmtpps AM335x timer capture code was added over 4 years ago.

So far as I can see none of them required anything but a normal GENERIC kernel.
