I have only seen Intel doing this, are there more people doing that?

As noted on patch [0/7] I still get patches for embedded x86 which
use ISA-style probing for embedded x86, e.g:
http://marc.info/?l=linux-gpio&m=138559852307673&w=2

At the same time some people are refining SFI (simple firmware
interface) support for GPIO, albeit I think that was for elder
embedded x86'es.

Yours,
