With this patchset in place I can crash the board using the following
sequence (SM8350-HDK):

- plug the USBC DP dongle
- run modetest at any mode, don't press Enter yet
- unplug the dongle
- press Enter to stop modetest

=> the board resets to Sahara.

Please ping me if you need any additional information from my side.
