For what it's worth, checkpatch reports at least the following:

   167: WARNING: DT binding docs and includes should be a separate patch. See: Documentation/devicetree/bindings/submitting-patches.rst
   180: WARNING: added, moved or deleted file(s), does MAINTAINERS need updating?
   193: WARNING: DT compatible string "nvidia,gb200-ut30b" appears un-documented -- check ./Documentation/devicetree/bindings/

Thanks,

Andrew
