[PATCH v3 4/6] arm64: dts: qcom: sm8450-hdk: Add QMP & DP to SuperSpeed graph

Neil Armstrong neil.armstrong at linaro.org
Tue May 23 00:15:48 PDT 2023


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 Type-C
connector, 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.
