In J721s2 EVM, DP0 HPD is not connected to correct HPD pin on SOC which results in HPD detect as always connnected, so when display is not connected driver continuously retries to read EDID and DPCD registers.
Where is the DP0 HPD connected to? Nowhere? If it's connected to a pin, can that pin be used as a GPIO? In other words, do we have a HPD, just not with mhdp, or is there just no HPD at all?
