Subject: [PATCH v2 3/3] arm64: dts: qcom: qcm6490-fairphone-fp5: Hook up
DisplayPort over USB-C
Extend the USB graph to connect the OCP96011 switch, the PTN36502
redriver, the USB controllers and the MDSS, so that DisplayPort over
USB-C is working.
Connect some parts of the graph directly in the SoC dtsi since those
parts are wired up like this in the SoC directly.
Signed-off-by: Luca Weiss <luca.weiss@...rphone.com>
