If anyone has any objections, please let me know. ------------------ From: Krishna Kurapati commit dc6ba95c6c4400a84cca5b419b34ae852a08cfb5 upstream. For Gen-1 targets like IPQ8074, it is seen that stressing out the controller in host mode results in HC died error: 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 And at this instant only restarting the host mode fixes it. Disable SuperSpeed instance in park mode for IPQ8074 to mitigate this issue.
