This was not known when adding support for V3U and V4H and a single SoC specific compatible was used. Before adding more SoC specific bindings for V4M add a family compatible fallback for Gen4. That way the driver only needs to be updated once for Gen4, and we still have the option to fix any problems in the driver if any testable differences between the SoCs are found. There are already DTS files using the V3U and V4H compatibles which needs to be updated to not produce a warning for DTS checks. The driver also needs to kept the compatible values to be backward compatible , but for new Gen4 SoCs such as V4M we can avoid this.
