Comment 39 for bug 1348890

Josh, thanks for the info. I had a good look at this, and unfortunately it looks a bit difficult to fix this in a sane way without regressing

    drm/i915: set DIDL using the ACPI video output device _ADR method return.

and https://bugzilla.kernel.org/show_bug.cgi?id=15054 at the same time.

Without that commit, we'd have more of a free hand in picking the device IDs for DIDL, and in particular making a sane mapping from our connectors, so we could update CPDL and CADL as well.

Lowering the priority for now.
