From 5b8baed4b88132c12010ce6ca1b56f00d122e376 Mon Sep 17 00:00:00 2001 From: Krishna Kurapati quic_kriskura@quicinc.com Date: Tue, 4 Jun 2024 11:36:58 +0530 Subject: [PATCH] arm64: dts: qcom: sc7180: Disable SuperSpeed instances in park mode
On SC7180, in host mode, it is observed that stressing out controller 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 instances in park mode for SC7180 to mitigate this issue.
