Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present for any node. Add unevaluatedProperties or additionalProperties as appropriate.

The QMC audio is an ASoC component which uses QMC (QUICC Multichannel
|
|
Controller) channels to transfer the audio data.
|
|
It provides as many DAI as the number of QMC channel used.
