to make sure I understand this correctly:
the license is then only valid for the bindings - is it fine if the
driver uses GPL-2.0-only?

I don't have any datasheet for these SoCs so all my knowledge is based
on the GPL-2.0-only driver from the Lantiq board support package
(called "UGW").
the .yaml file is 100% my own work so I'm fine with having GPL-2.0 OR
BSD-2-Clause
however, that still has to be compatible with my driver, which I chose
to be GPL-2.0-only because that's the license from the Lantiq board
support package
