I don't have a better solution than this.

So neither devicetree or ACPI entries exists for the xHC part of this dwc3 controller?

A pure platform device is created, and it matches and binds to xhci-plat driver by "xhci-hcd" name.
I guess we have no way to identify this dwc3 xhci controller in xhci-plat.c, and set quirks there,
like all those devicetree xhci devices that we set quirks based on .compatibility. 

Thanks
Mathias
