Perhaps this should match the dts files license...

Hi Rob:
What's the means of the "dts files license"?

You include this into .dts files and those are dual licensed. The
licenses should match (or be compatible).

I'm not clear understand that.
I found that there are almost similar "/* SPDX-License-Identifier: GPL-2.0 */" license contained in the files of the /include/dt-bindings/phy folder.

Yes, licenses are a mess. But what other files in
include/dt-bindings/phy have don't matter. Where you use this file is
what matters.
