If the latter, then "num" is definitely way too ambiguous. Konrad

A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

Add a dt-binding to describe the definition of enabling the Q6 USB backend device for audio offloading. The node carries information, which is passed along to the QC USB SND class driver counterpart. These parameters will be utilized during QMI stream enable requests.
