I have absolutely no clue either.

What I know is that there is a device tree compiler warning that can
be turned on, and
it generates these warnings a lot. The actual problems have been in
the DTS files
forever. They just recently started to look into them.

It has nothing to do with the GPIO tree whatsoever, so I wonder if it
is a side effect of
something else?
