What is generic here? It's an acronym of some specific device name. Best regards, Krzysztof

That's obvious and my comment was not about it. Second time... This is my unlucky day... I said, why do you even want to enforce name which is not generic, since the names should be generic? I assume you read the DT specification: https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation Best regards, Krzysztof
