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/ for instructions). Maybe you need to update your dtschema and yamllint. Don't rely on distro packages for dtschema and be sure you are using the latest released dtschema. Please run scripts/checkpatch.pl and fix reported warnings. After that, run also `scripts/checkpatch.pl --strict` and (probably) fix more warnings. Some warnings can be ignored, especially from --strict run, but the code here looks like it needs a fix. Feel free to get in touch if the warning is not clear. Best regards, Krzysztof
