Filename matching compatible, so qcom,qdu1000-tlmm.yaml

You have now bindings for your new SoC and you still did not run them
against your own DTS... The purpose of DT schema is not only to have
them, but actually to use them.

There is no point for us to do manual review if automated tools can do
the work, right?

So please test your DTS.

Best regards,
Krzysztof
