Li Jun 9d5333c931 usb: cdns3: host: fix endless superspeed hub port reset ... When usb 3.0 hub connect with one USB 2.0 device and NO USB 3.0 device, some usb hub reports endless port reset message. [ 190.324169] usb 2-1: new SuperSpeed USB device number 88 using xhci-hcd [ 190.352834] hub 2-1:1.0: USB hub found [ 190.356995] hub 2-1:1.0: 4 ports detected [ 190.700056] usb 2-1: USB disconnect, device number 88 [ 192.472139] usb 2-1: new SuperSpeed USB device number 89 using xhci-hcd [ 192.500820] hub 2-1:1.0: USB hub found [ 192.504977] hub 2-1:1.0: 4 ports detected [ 192.852066] usb 2-1: USB disconnect, device number 89 The reason is the runtime pm state of USB2.0 port is active and USB 3.0 port is suspend, so parent device is active state. cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/xhci-hcd.1.auto/usb2/power/runtime_status suspended cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/xhci-hcd.1.auto/usb1/power/runtime_status active cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/xhci-hcd.1.auto/power/runtime_status active cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/power/runtime_status active So xhci_cdns3_suspend_quirk() have not called. U3 configure is not applied. move U3 configure into host start. Reinit again in resume function in case controller power lost during suspend.
