I see. Do you have an example of a panel controller that does this? I don't see that much value in doing this since you want the DTS to describe the actual HW and so want the panel I believe. But also there isn't an of_device_id entry for this fallback controller compatible string. Feel free to propose that as a follow-up if you think it is worth doing so. Best regards, Javier
