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 ti/omap/am335x-evmsk.dtb' for 20240411231130.386222-1-jm@ti.com: arch/arm/boot/dts/ti/omap/am33xx.dtsi:20.10-43.4: ERROR (path_references): /aliases: Reference to non-existent node or label "pruss_uart" also defined at arch/arm/boot/dts/ti/omap/am335x-evmsk.dts:32.10-35.4 ERROR: Input tree has errors, aborting (use -f to force output) make[4]: *** [scripts/Makefile.lib:427: arch/arm/boot/dts/ti/omap/am335x-evmsk.dtb] Error 2 make[3]: *** [scripts/Makefile.build:485: arch/arm/boot/dts/ti/omap] Error 2 make[3]: Target 'arch/arm/boot/dts/ti/omap/am335x-evmsk.dtb' not remade because of errors. make[2]: *** [scripts/Makefile.build:485: arch/arm/boot/dts/ti] Error 2 make[2]: Target 'arch/arm/boot/dts/ti/omap/am335x-evmsk.dtb' not remade because of errors. make[1]: *** [/home/rob/proj/linux-dt-testing/Makefile:1392: ti/omap/am335x-evmsk.dtb] Error 2 make: *** [Makefile:240: __sub-make] Error 2 make: Target 'ti/omap/am335x-evmsk.dtb' not remade because of errors.

The AM335x SK routes the PRUSS UART pins to the Zigbee header. PRUSS UART is enabled and can be tested using the Zigbee header. Since there are two UARTS, add alias node to be able to test PRUSS UART reliably from userspace.
