My bot found new DTB warnings on the .dts files added or changed in this
series.

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 freescale/imx8mp-aristainetos3-adpismarc.dtb freescale/imx8mp-aristainetos3-helios.dtb freescale/imx8mp-aristainetos3-proton2s.dtb' for 20241105064206.43626-1-hs at denx.de:
