I think it would be easier to have a flat list of compatibles and handle all the differences inside the driver. For example, for sdm845 we simply reused sc7180 config internally, while keeping separate compatible strings. > > Sure, but the doc reports the SM8350, SM8450 and SM550 has the exact same IP version, isn't fallback for that cat ? Exactly. What's the trouble with the list Neil created? Best regards, Krzysztof
