--- Comment #4 from Arek Hiler <arkadiusz.hiler at intel.com> ---
Seems like we have two issues here with the same root-cause: LSPCon
What do they mean for the user: somtimes when you plug the cable in nothing
happens - the connector stays disconnected.
Raising the priority to high and changeing feature to display/LSPCON.
Note: DP-1 is connected to LSPCon and exposed as a HDMI port.
Issue 1. LSPcon does not wake up on plug and we don't even get a hotplug event

and so we have failed & exited after HTOPLUG_TIMEOUT=20s
Issue 2. LSPcon wakes up, we get a hotplug but the full initialization fails
and the port is still considered DISCONNECTED
