Added the following SPDX-License-Identifier: (GPL-2.0+ OR BSD) in the
middle of the top of file comment.

There are two problems with that:

1) BSD is not a valid SPDX identifier. See https://spdx.org/licenses/

   You need to say which BSD variant you mean.

2) Please put the License identifier to the place which is defined in
   Documentation/process/licenses.rst, i.e. the first line of the dts file
   and not to some random place.

Thanks,
