The SM8450 & SM350 shares the same DT TX IP version, use the

Neil, Krzysztof, I'm not convinced that this is worth all the troubles. 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 ?
