[U-Boot] DWC3 USB driver regression

Hi.

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

I did git-bisect, and the first bad commit is

7c839ea70c4991e8d4c322e074359ac5e155d59d is the first bad commit commit 7c839ea70c4991e8d4c322e074359ac5e155d59d Author: Neil Armstrong narmstrong@baylibre.com Date: Wed Apr 11 17:08:01 2018 +0200

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?
