• prefix_name:

No underscores in node names, missing vendor prefix... but more important: I don't understand the need for this property. Description copies property name so it is not useful.

And these comments as well.

The prefix_name is used to distinguish the dapm and kcontrol of each individual codec. And I will update name of the property

• everest,dmic-enabled:
• $ref: /schemas/types.yaml#/definitions/flag
• description:

•  The property is a choice between PDM and AMIC
  

No supplies?

I will drop the property

I did not comment about dmic, but meant missing power supplies, which usually are placed here.

I apologize for misunderstanding your comment. But we don't have properties about the power supplies
