The USB phy of Sophgo CV18XX series SoC needs to sense a pin called
"VBUS_DET" to get the right operation mode. If this pin is not
connected, it only supports setting the mode manually.
Add USB phy bindings for Sophgo CV18XX/SG200X series SoC.

I'm having a bit of trouble finding the v3 etc, could you provide a
link?
I think what is here is sane, but I want to make sure that review
comments on previous versions have been addressed. "dfn:" searches for
both driver and binding filenames turned up nothing.

Thanks. I think this patch looks okay, but probably worth Rob or Krzysztof taking a look, even if you seem to have removed the props that were objected to.
