We were recently bitten by drm_edid_to_eld() clearing the connector type, and us failing to set it back for DP. Here's a few ELD related patches to try to unify ELD handling and make it a bit simpler for drivers to get it right.
Apologies for the massive Cc list; it's the maintainers of all drivers that call drm_edid_to_eld(). I'm open to splitting up patch 6 to driver specific patches as needed, but I'd think it would be just fine to merge via drm-misc as-is too. BR, Jani.
