Any schema file with an error shows up twice. First there's all the
specific errors with details. Then there's what you reference which is
all the schemas that we're skipping. If you set DT_SCHEMA_FILES now,
you should only see the second case for other schema files.

So it's probably better to reference the actual error:

Documentation/devicetree/bindings/media/qcom,sc7280-venus.yaml:
properties:power-domain-names: {'minItems': 2, 'maxItems': 3, 'items':
[{'const': 'venus'}, {'const': 'vcodec0'}, {'const': 'cx'}]} should
not be valid under {'required': ['maxItems']}
 hint: "maxItems" is not needed with an "items" list
 from schema $id: http://devicetree.org/meta-schemas/items.yaml#
