Hi.


I found DWC3 usb driver on UniPhier SoC family
not working.

    usb: host: dwc3: Add support for multiple PHYs

    DWC3 Ips can have more than 1 PHY for USB2 and 1 PHY for USB3, add support
    for a generic number of PHYs and adapt the code to handle a generic
    number of PHYs.

If I revert this commit, I can get the USB on my board working.

Any insight about the cause of the problem?
