My mistake. Thanks for spotting that.
I have my company agreement for the 2 dual models: "OR BSD-2-Clause" and "OR BSD-3-Clause".
We expect to conform to DT bindings preferred licensing model. Indeed the kernel documentation explicitly mention "GPL-2.0-only OR BSD-2-Clause".
We prefer to conform with it. I'll update my patch.

By the way, I'll fix Lee Jones e-mail address that is deprecated.

(fyi: I've sent PATCH v2: https://lore.kernel.org/lkml/20240617092016.2958046-1-etienne.carriere@foss.st.com/)

BR,
Etienne
