I succesfully tested this on the SM8450 HDK, and the following works:
- USB-C to HDMI, both directions
- USB-C to DP cable to DP display, both directions
- USB-C to USB SuperSpeed, both directions
- USB-C to USB-C, both directions, enables SuperSpeed Plus Gen 2x1

Tested-by: Neil Armstrong <neil.armstrong@...aro.org> # on HDK8450

Thanks,
