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.
