Rob and other dt folks,

In continue to disscussion with Boris below, Looking at the checkpatch 
check:

    if ($realfile =~ m@^Documentation/devicetree/bindings/@ &&
        not $spdx_license =~/GPL-2\.0.*BSD-2-Clause/) {

It wants the whole string "GPL-2.0-only OR BSD-2-Clause" and my oatch has only "GPL-2.0-only".

Now, looking at a bunch of .yaml DT files, there are all kinds of formatting:

$ git grep -h SPDX *.yaml | sort | uniq -c
       3 1:# SPDX-License-Identifier: (GPL-2.0)
     313 1:# SPDX-License-Identifier: GPL-2.0
       9 1:# SPDX-License-Identifier: GPL-2.0+

       4 1:# SPDX-License-Identifier: (GPL-2.0-only or BSD-2-Clause)

       3 1:# SPDX-License-Identifier: (GPL-2.0+ OR MIT)
       3 1:# SPDX-License-Identifier: (GPL-2.0+ OR X11)

And the patch which did rule is:

commit 50c92900214dd9a55bcecc3c53e90d072aff6560
Author: Lubomir Rintel<lkundrak@v3.sk>
Date:   Mon Apr 6 20:11:13 2020 -0700

     checkpatch: check proper licensing of Devicetree bindings

     According to Devicetree maintainers (see Link: below), the Devicetree
     binding documents are preferrably licensed (GPL-2.0-only OR BSD-2-Clause).

     Let's check that.  The actual check is a bit more relaxed, to allow more
     liberal but compatible licensing (e.g.  GPL-2.0-or-later OR BSD-2-Clause).


Will love your help.
This patch already have your (Rob) Reviewed-by so Boris and myself are unsure what is the right thing to do now.

Thanks,
Talel.
