The only difference is 'reset' is required in one? Perhaps better to just not make 'reset' required til we figure out how to handle a conditional like this. Seems like we discussed this and I probably said to split things? I guess it's a judgement call depending on how different things are. Possibly, we could handle this case like this: allOf: - $ref: allwinner,sun4i-a10-spdif.yaml properties: resets: maxItems: 1 required: - resets Plus we'd need the 'allwinner,sun6i-a31-spdif' and other compatibles in both files. Note that you can't use 'additionalProperties: false' in either file in this case. I don't really love this solution though. Rob
