As I already mentioned in the cover letter and in the commit message, I
just don't know which criteria makes most sense here.
On a general note, I would say that chances that this exactly IP core
with the same version number will appear on some other silicon which
doesn't support the control mode register in an AM33xx fashion, is not
necessarily negligible.
So what that new compatible string denotes is the cpsw in a version as
found on am3352 SoCs, which is actually exactly what it does.
I don't have a strong opinion here, but see your point. I just don't
have a better idea on how to treat that.
