| Subject: arm64: dts: qcom: msm8998: Disable SS instance in Parkmode for USB |
| |
| From: Krishna Kurapati <quic_kriskura@quicinc.com> |
| |
| commit 0046325ae52079b46da13a7f84dd7b2a6f7c38f8 upstream. |
| |
| For Gen-1 targets like MSM8998, 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 MSM8998 to mitigate this issue. |
