Run checkpatch (your question kinds of point to the fact that you did not run it...): WARNING: DT binding documents should be licensed (GPL-2.0-only OR BSD-2-Clause) If your new bindings use copied/derivative description or DTS code which is licensed as only GPL-2.0, the bindings itself as derivative work might need to stay as GPL-2.0 as well. Unless copyright holders agree to re-license this as GPL2-OR-BSD. As representing company, your patch might be enough to re-license, but maybe other people contributed. I don't know. I just wanted to be sure that you use GPL-2.0 in purpose, because GPL2-OR-BSD cannot be used. Best regards, Krzysztof
