ok I got this for USB3_SSPHY_STATUS
[ 3.057122] cdns3-imx 5b110000.usb3: wait clkvld timeout 0xb0b03827
Unfortunally my imx8qm spec is incomplete regarding the USB3_SSPHY_STATUS register.
this are my related DTS nodes:

I'am also using the SCU related clock patches from here:

Thx for your comments,
