| Subject: [PATCH] arm64: dts: g12-common: add parkmode_disable_ss_quirk on DWC3 |
| controller |
| |
| commit a81bcfb6ac20cdd2e8dec3da14c8bbe1d18f6321 upstream. |
| |
| When high load on the DWC3 SuperSpeed port, the controller crashes with: |
| [ 221.141621] xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command. |
| [ 221.157631] xhci-hcd xhci-hcd.0.auto: Host halt failed, -110 |
| [ 221.157635] xhci-hcd xhci-hcd.0.auto: xHCI host controller not responding, assume dead |
| [ 221.159901] xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command. |
| [ 221.159961] hub 2-1.1:1.0: hub_ext_port_status failed (err = -22) |
| [ 221.160076] xhci-hcd xhci-hcd.0.auto: HC died; cleaning up |
| [ 221.165946] usb 2-1.1-port1: cannot reset (err = -22) |
| |
| Setting the parkmode_disable_ss_quirk quirk fixes the issue. |
