For the former case, which is the most general, which can be used as a fallback? How about something like: - compatible: should contain: * "xlnx,ps7-ddrc-1.00.a" for <DESCRIPTION HERE> * "xlnx,ps7-ddrc" for any compatible variant Is there any need at all for the "xlnx,ps7-ddrc" string? The driver doesn't care about it.
