+Porting and alternative licences
+=================================
+
+This driver started as a derivative of linux/drivers/net/can/slcan.c
+and my thanks go to the original authors for their inspiration, even
+after almost none of their code is left.
+
+This code barely bears any resemblance to slcan anymore, and whatever
+may be left is Linux specific boilerplate anyway, however I am leaving
+the GPL-2.0 identifier at the top just to be sure.
+
+Please feel free to use my own code, especially the ELM327 communication
+logic, in accordance with SPDX-License-Identifier BSD-3-Clause to port
+this driver to other systems.
+
+If in doubt, feel free to ask me to clarify which code is mine.
+

 Thanks
