From: Krishna Kurapati Date: Thu, 4 Jul 2024 15:28:45 +0000 (+0530) Subject: arm64: dts: qcom: sm6115: Disable SS instance in Parkmode for USB X-Git-Tag: v6.10.2~6 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=cba936e34ba5c35c036c9615ebdd0a3fbf9c6ee5;p=thirdparty%2Fkernel%2Fstable.git arm64: dts: qcom: sm6115: Disable SS instance in Parkmode for USB commit 074992a1163295d717faa21d1818c4c19ef6e676 upstream. For Gen-1 targets like SM6115, 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 SM6115 to mitigate this issue.
