Exactly. In particular we don't want people to get the wrong idea about
where we are heading, so making it possible to use this code on embedded
systems for me is a reason *not* to take the patch.

People are trying to deploy ACPI-based embedded x86, and most of the
ACPI/DT integration discussion seems to have been based on the idea that
this is a worthwhile thing to support.

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.
