From dc6ba95c6c4400a84cca5b419b34ae852a08cfb5 Mon Sep 17 00:00:00 2001 From: Krishna Kurapati quic_kriskura@quicinc.com Date: Thu, 4 Jul 2024 20:58:42 +0530 Subject: [PATCH] arm64: dts: qcom: ipq8074: Disable SS instance in Parkmode for USB

For Gen-1 targets like IPQ8074, 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 IPQ8074 to mitigate this issue.
