commit f33cf4647b59155c30ead94492eefe32e2cae0ec
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8IKRU

--------------------------------

commit 7e6f3b6d2c352b5fde37ce3fed83bdf6172eebd4 upstream.

The AMD VanGogh SoC contains a DesignWare USB3 Dual-Role Device that can be
operated as either a USB Host or a USB Device, similar to on the AMD Nolan
platform.

be6646bf ("PCI: Prevent xHCI driver from claiming AMD Nolan USB3 DRD
device") added a quirk to let the dwc3 driver claim the Nolan device since
it provides more specific support.

Extend that quirk to include the VanGogh SoC USB3 device.
