If anyone has any objections, please let me know. ------------------ From: Konrad Dybcio commit 27f94b71532203b079537180924023a5f636fca1 upstream. 2290 was found in the field to also require this quirk, as long & high-bandwidth workloads (e.g. USB ethernet) are consistently able to crash the controller otherwise. 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.
