We’re trying to bring up displayport on a custom carrier board without the USB-C controller. We have removed the typec-port from the device-tree, and have verified that it is removed from the dtb.
When connecting to a monitor the monitor registers a connection, and displays a selected resolution as expected. Observing the AUX-pins shows that there is some communication, however there is no image on screen.

There is also a kernellog, where there does not seem to be any plug in-event, and the extcon AUX2 (HDMI) lines keep repeating enable/disable indefinatly.
We have routed DP0 to the connector according to the design guide.
Hope you are able to help fix this issue
