From: Krishna Kurapati Date: Thu, 4 Jul 2024 15:28:46 +0000 (+0530) Subject: arm64: dts: qcom: sm6350: Disable SS instance in Parkmode for USB X-Git-Tag: v6.10.2~12 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=aa38865e86565eed098b0a3661c3068f829f6f4f;p=thirdparty%2Fkernel%2Fstable.git arm64: dts: qcom: sm6350: Disable SS instance in Parkmode for USB commit c5d57eb7d06df16c07037cea5dacfd74d49d1833 upstream. For Gen-1 targets like SM6350, 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 SM6350 to mitigate this issue.
