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:

};

interrupt-names = "host", "peripheral", "otg";
reg = <0x5B130000 0x10000>, /* memory area for HOST registers */
<0x5B140000 0x10000>, /* memory area for DEVICE registers */
<0x5B120000 0x10000>; /* memory area for OTG/DRD registers */
reg-names = "xhci", "dev", "otg";
phys = <&usbphynop2>;
phy-names = "cdns3,usb2-phy";

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

Thx for your comments,
Best regards,
