Having stumbled upon a similar issue for non-VGA connectors, would it be better if this is moved to the drm_edid.c? We already support per-connector overrides and then loading the EDIDs from /lib/firmware via the edid-firmware. Would it make sense to extend / reuse the same mechanism? For example, enough of the LVDS panels come with the EDID (and EDID lines) being wired, but in some case we might want to supply the EDID (via the DT or via the request_firmware()). -- With best wishes Dmitry
