Unfortunately, I don't know how else to do this other than this broken, unreasonable and insane way. This has already been discussed at length in a few other places. Without some help from the drm layer, I don't see any other way to do this than to enumerate the possible bridges in each drm driver. I based the current set off the "Add some missing bits for exynos5250-snow" series I sent up a little while ago. This set was sent to the relevant dt people, acked by Olof, and there are no outstanding review comments. Since it's required for me to test on Real Hardware, I assumed this was an appropriate base. If you think this is _broken_, unreasonable, and insane, I'd love to hear an alternative.
