I suggested the one in second reply: lenovo,yoga-slim-whatever-model-it-is-ec If you have any indication that Qualcomm firmware from a reference board was used as a reference, it could be used as fallback, but I do not believe you can have such indication considering downstream source code does not exist and all other docs are confidential. Therefore lenovo EC is the first implementation we see and we know anything about. Best regards, Krzysztof
