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 New warnings running 'make CHECK_DTBS=y for arch/arm64/boot/dts/exynos/' for 20250213000226.277-1-wachiturroxd150@gmail.com: Error: arch/arm64/boot/dts/exynos/exynos990-r8s.dts:122.1-10 Label or path usi_uart not found Error: arch/arm64/boot/dts/exynos/exynos990-r8s.dts:127.1-10 Label or path serial_0 not found Error: arch/arm64/boot/dts/exynos/exynos990-r8s.dts:131.1-13 Label or path usi_bt_uart not found Error: arch/arm64/boot/dts/exynos/exynos990-r8s.dts:136.1-10 Label or path serial_1 not found FATAL ERROR: Syntax error parsing input tree make[3]: *** [scripts/Makefile.dtbs:131: arch/arm64/boot/dts/exynos/exynos990-r8s.dtb] Error 1 make[2]: *** [scripts/Makefile.build:465: arch/arm64/boot/dts/exynos] Error 2 make[2]: Target 'arch/arm64/boot/dts/exynos/exynos990-r8s.dtb' not remade because of errors. make[1]: *** [/home/rob/proj/linux-dt-testing/Makefile:1464: exynos/exynos990-r8s.dtb] Error 2 make: *** [Makefile:251: __sub-make] Error 2 make: Target 'exynos/exynos8895-dreamlte.dtb' not remade because of errors. make: Target 'exynos/exynos850-e850-96.dtb' not remade because of errors. make: Target 'exynos/exynos7885-jackpotlte.dtb' not remade because of errors. make: Target 'exynos/exynos990-x1slte.dtb' not remade because of errors. make: Target 'exynos/exynos5433-tm2.dtb' not remade because of errors. make: Target 'exynos/exynos990-r8s.dtb' not remade because of errors. make: Target 'exynos/exynos7-espresso.dtb' not remade because of errors. make: Target 'exynos/google/gs101-oriole.dtb' not remade because of errors. make: Target 'exynos/google/gs101-raven.dtb' not remade because of errors. make: Target 'exynos/exynosautov920-sadk.dtb' not remade because of errors. make: Target 'exynos/exynosautov9-sadk.dtb' not remade because of errors. make: Target 'exynos/exynos990-c1s.dtb' not remade because of errors. make: Target 'exynos/exynos9810-starlte.dtb' not remade because of errors. make: Target 'exynos/exynos990-x1s.dtb' not remade because of errors. make: Target 'exynos/exynos5433-tm2e.dtb' not remade because of errors.
