H A Dxhci-dwc3.c5e8c228de78728ff82f72c9525a4361f4bc1f6dc Mon Sep 09 18:52:39 UTC 2019 Neil Armstrong <narmstrong@baylibre.com> UPSTREAM: usb: xhci-dwc3: Add support for dis_u2_susphy_quirk

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.
