TUSB8020B-Q1: When linux start finish. There are too many dmesg with usb port which hub attached.

Part Number: TUSB8020B-Q1

Hello, TI

Our usb hub can work normal but there are too many log as below show:

[ 1226.069410] msm-dwc3 a800000.ssusb: DWC3 in low power mode
[ 1226.074475] msm-dwc3 a800000.ssusb: DWC3 exited from low power mode
[ 1227.078054] msm-dwc3 a800000.ssusb: DWC3 in low power mode
[ 1227.079939] msm-dwc3 a800000.ssusb: DWC3 exited from low power mode
[ 1228.078537] msm-dwc3 a800000.ssusb: DWC3 in low power mode
[ 1228.083680] msm-dwc3 a800000.ssusb: DWC3 exited from low power mode

It looks like when usb controller goto low power mode. The hub will wake up it right away. Out other usb chip doesn't have this case.

Can you help us to analysis the problem? Thanks.
