This file looks quite different then the one I see on kernel.org with that revision id. So you are sure you
imported that one?

This file is dual licensed upstream, keep it that way.
The comment will claim it’s a X11 license but the license text below

Not sure if this should go into a separate dtsi. One of the maintainer will have
