What do you think? Doesn't matter what's in the driver, it can use this compatible. But experience has shown that a compatible for a licensed IP is never sufficient. There are versions of the blocks, configuration options, and integration differences. I'm not asking you to add any SoC specific compatible now unless you are working on a particular SoC, but just state one is needed.
