LSPCON? Cc: Jim.
Most likely this is LSPCON again based off of what I'm seeing from the VBT in the dmesg output. CC: Paulo, who is slated to upstream LSPCON patches once VPG posts them.
Increasing priority due to current platform experience impact

This is expected. There are two ways to connect HDMI to the APL RVPs: via the DDI1 DP++ plug with an DP->HDMI dongle, or via the DDI0 HDMI plug which is connected to the SoC through the LSPCON converter. You seem to be using the second scenario with LSPCON being in the protocol converter mode (configured as such by BIOS). In that case the connection will show up as a DP connector. I'm suggesting closing this based on the above.

There may be any number of *other* problems with LSPCON, and other bugs have already been filed on them, but this will not be fixed. (Can't be fixed in any sane way, really.)
