[PATCH 6.9 19/29] arm64: dts: qcom: msm8996: Disable SS instance in Parkmode for USB

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Krishna Kurapati <quic_kriskura@xxxxxxxxxxx>

commit 44ea1ae3cf95db97e10d6ce17527948121f1dd4b upstream.

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.
