Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments. If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date: pip3 install dtschema --upgrade This patch series was applied (using b4) to base: Base: using specified base-commit d086c886ceb9f59dea6c3a9dae7eb89e780a20c9 If this is not the correct base, please add 'base-commit' tag (or use b4 which does this automatically) New warnings running 'make
