From 44ea1ae3cf95db97e10d6ce17527948121f1dd4b Mon Sep 17 00:00:00 2001 From: Krishna Kurapati quic_kriskura@quicinc.com Date: Thu, 4 Jul 2024 20:58:47 +0530 Subject: [PATCH] arm64: dts: qcom: msm8996: Disable SS instance in Parkmode for USB
For Gen-1 targets like MSM8996, 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 MSM8996 to mitigate this issue.
