The same change has been made for a number of SoCs in [1], but QCM2290 somehow escaped the list (even though the very closely related SM6115 was there). Upon a controller crash, the log would read: xhci-hcd.12.auto: xHCI host not responding to stop endpoint command xhci-hcd.12.auto: xHCI host controller not responding, assume dead xhci-hcd.12.auto: HC died; cleaning up Add snps,parkmode-disable-ss-quirk to the DWC3 instance in order to prevent the aforementioned breakage.
