In most other cases I think your expectation would hold though. Perhaps would be suitable to put the pmic_glink in sc8280xp.dtsi but disable it, and then add connectors in the device.

With support for the QMP combo phy to react to USB Type-C switch events, introduce it as the next hop for the SuperSpeed lanes of the two USB Type-C connectors, and connect the output of the DisplayPort controller to the QMP combo phy. This allows the TCPM to perform orientation switching of both USB and DisplayPort signals.
