Although functionally unused, there is one more connector node that runs between QMPPHY and DWC3 node. For example in [1], please check "usb_dp_qmpphy_usb_ss_in" and "usb_1_dwc3_ss" Would be good to check why it is missing and add it further.

I checked, there's an extra endpoint for usb_?_qmpphy_usb_ss_in and usb_?_qmpphy_dp_in. usb_?_qmpphy_usb_ss_in are defined (and "wired") between port@1 of usb_?_qmpphy and port@1 of usb_?_dwc3, in sc8280xp.dtsi. On port@2 of the qmpphy is usb_?_qmpphy_dp_in as endpoint, which is further defined in sc8280xp-microsoft-blackrock.dts as connecting to mdss0_dp?_out. Maybe that's wrong, it's the same as in sc8280xp-lenvo-thinkpad-x13s.dts. with best regards Jens
