Squash it.
Yes, I made a single commit for device tree.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/

Really? You just added these lines. There is no point in adding a new
line and immediately changing it.
This points how your split is artificial and not helpful.

Now I have a single commit for device tree.
