6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Krishna Kurapati <quic_kriskura@xxxxxxxxxxx> [ Upstream commit 5b8baed4b88132c12010ce6ca1b56f00d122e376 ] On SC7180, in host mode, it is observed that stressing out controller 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 instances in park mode for SC7180 to mitigate this issue.
