It means that the driver currently matches on one of the first three strings that don't carry that annotation. > If the former, what is important is what are the valid combinations of > compatible properties and that is not captured here. In other words, > what is the fallback compatible string for each chip? The intention was to try to be helpful: to document that anyone adding a "nvidia,tegra132-pcie" compatible string would also need to add one of the other strings as a fallback. Would you like that to be documented in a different way, or removed? - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
