Ignoring everything else, because I really want Krzysztof or Rob to
review this rather than me, but what's going on here with the
compatibles?
What hardware do "usbNphy" and "rtd-usbNphy" represent?

You have device-specific compatibles, which is great, but you also allow
only those two generic ones. I had a _brief_ look at the driver, and it
seems like there is no decision making done based on the compatibles,
only on the properties. Is that correct?
If it is, I would understand having "realtek,usb3phy" as a fallback
compatible for "realtek,rtd1619-usb3phy", but I do not get the current
setup.

Also, I really think this should be broken down into two patches, one
for each of USB 2 & 3.

Cheers,
Conor.
