From cf4d6d54eadb60d2ee4d31c9d92299f5e8dcb55c Mon Sep 17 00:00:00 2001 From: Krishna Kurapati quic_kriskura@quicinc.com Date: Thu, 4 Jul 2024 20:58:48 +0530 Subject: [PATCH] arm64: dts: qcom: sdm845: Disable SS instance in Parkmode for USB
For Gen-1 targets like SDM845, 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 SDM845 to mitigate this issue.
