Subject[PATCH v4 3/3] arm64: dts: g12-common: add parkmode_disable_ss_quirk on DWC3 controller
Date
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.
