[PATCH v5 04/14] dt-bindings: phy: qcom,sc7180-qmp-usb3-dp-phy: Add ports as an optional

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add ports as an optional

port@0 to receive an orientation-switch message from the Type-C port or
redriver

port@1 to subsequently transmit the orientation-switch on once the PHY has
finished doing its orientation turn-around.
