[PATCH v4 03/18] dt-bindings: phy: qcom,sc7180-qmp-usb3-dp-phy: Add orientation-switch as optional

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

 



orientation-switch it the standard declaration to inform the Type-C mux
layer that a remote-endpoint is capable of processing orientation change
messages.

Add as an optional since not all versions of the dp-phy currently support
the orientation-switch.
