1. It is you who should compare the decompiled DTS, not us. For example:
$ for i in dts-old/*/*dtb dts-old/*/*/*dtb; do echo $i; crosc64
scripts/dtc/dtx_diff ${i} dts-new/${i#dts-old/} ; done

$ for i in dts-old/*/*dtb dts-old/*/*/*dtb; do echo $i; crosc64
fdtdump ${i} > ${i}.fdt ; crosc64 fdtdump dts-new/${i#dts-old/} >
dts-new/${i#dts-old/}.fdt ; diff -ubB ${i}.fdt
dts-new/${i#dts-old/}.fdt ; done

2. Split it per arm architectures (and proper subject prefix - not
"arch") and subarchitectures so maintainers can pick it up.

3. The subject title could be more accurate - there is no fix here
because there was no errors in the first place. Requirement of DWC
node names comes recently, so it is more alignment with dtschema.
Otherwise automatic-pickup-stable-bot might want to pick up... and it
should not go to stable.

Best regards,
Krzysztof
