Change include/dt-bindings/mfd/st,stpmic1.h license model from GPLv2.0
only to dual GPLv2.0 or BSD-3-Clause. I have every legitimacy to request
this change on behalf of STMicroelectronics. This change clarifies that
this DT binding header file can be shared with software components as
bootloaders and OSes that are not published under GPLv2 terms.

In CC are all the contributors to this header file.

The usual dual license for bindings is BSD-2-Clause, was there a
specific request for the 3 version?

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
