That's not correct commit msg. You just pasted subject.

Not documented. Checkpatch should fail, so it means you did not run it.
Be sure your new platform passes:
1. checkpatch
2. dtbs_check
3. dtbs W=1
You need changes to bindings.

Not documented. The same all others. If there is dependency, you should
clearly communicate it.

Fails tests. Shouldn't this be serial?

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).
There is little point to review stuff which is being pointed out by
tools. First, fix your DTS to pass the tests. Then send for review.
