Devices are not generic. This is very confusing and commit msg does not help me. Compatibles *must* be specific, see writing-bindings. Best regards, Krzysztof

Devices are not generic. This is very confusing and commit msg does not help me. Compatibles *must* be specific, see writing-bindings. I guess I see this a generic fallback, that handles any dsi panel as long as the correct timing etc is specified in devictree, similar to what panel-dpi is in panel-dpi.yaml Maybe phrasing it similar to panel-dpi.yaml is better? >Best regards, >Krzysztof Best regards /Johan

But panel-dpi is quite different. You always have two compatibles. I don't see two compatibles here. Best regards, Krzysztof
