Not really, the way we works usually is that the compatible is the one
from the first SoC that implemented that IP. If the rev C has the same
IP than rev B, then we're using the rev B compatible.

Though, I'd agree with you. We should have a single compatible in the
DT, a generic one, that would trigger the auto-detection, and might
change it to the rev A one, but the rev B doesn't make much sense.
