This quirk is necessary for the Amlogic GXL SoCs otherwise the Port 2 PHY doesn't get out of suspend and U-Boot resets the board after:
XHCI timeout on event type 33... cannot recover. BUG: failure at drivers/usb/host/xhci-ring.c:474/xhci_wait_for_event()! BUG!
This quirk is also handled in the dwc3 core code, but until the xhci-dwc3 driver uses the dwc3 core, the quirk must be handled here to fix USB support on the Amlogic libretech-cc and libretech-ac board when a device is only plugged in the OTG port.

Should I take it into my amlogic tree or you'll handle it ?
Thanks, Neil
