The Broadcom Vulcan chip (now Cavium ThunderX2) uses the same USB PHY
from what I understand. Our hardware team reports that there are some
failures seen without the a custom PHY driver.

Do you require this PHY driver on regular operation on Stingray? Or is
this for some specific functionality? I am asking since the issue
reported here is on switching between a USB 3.0 and USB 2.0 devices.

Any plans on submitting this driver again?

Thanks,
JC
