Well, there is nothing specific about the Berlin CI. Some subsystems
use the 'generic' keyword in these cases. Do you see a particular reason
I should use some Berlin related compatible here?
Not must, one suggestion is: can you change the compatible string
to "chipidea-usb-generic"?
I don't know about ChipIdea/ARC/DW's product portfolio but I guess
the compatible should also carry '2.0' or 'usb2' in it. Or we just
use some version number like 'chipidea,ci13000' or 'chipidea,ci13xxx'.
The recommended format for compatible string is: "manufacturer,model",
I agree with "chipidea,ci13xxx", thanks.
I think we should probably avoid using wildcards in the compatible
string.
