The DT bindings are used by U-Boot and BSD too, what if
their drivers use it?

It's a bit confusing but we're essentially maintaining the bindings
for those other projects as well, and it's why, for a good reason,
DT maintainers originally wanted to split out the bindings to a
separate repo. (This didn't happen because nobody wants the
job of driving and maintaining that, binding maintainers have
enough trouble as it is.)

I'd say just apply the patch.
