[PATCH v3 4/9] arm64: dts: qcom: sm8250: add a link between DWC3 and QMP PHY
Posted by Dmitry Baryshkov 1 year, 10 months ago
The SuperSpeed signals originate from the DWC3 host controller and then
are routed through the Combo QMP PHY, where they are multiplexed with
the DisplayPort signals. Add corresponding OF graph link.
