Display output does not work when connecting a AM625 BeaglePlay board to a DVI monitor, because the it66121 bridge driver assumes that the sink type is always HDMI. This patch series fixes the issue.
Patch #1 moves the transmission mode and AVI infoframes enablement to the .atomic_enable handler, because currently this logic is in the .mode_set handler but that is called before .atomic_enable that is where the query of the connector is done (that contains the display sink type). Patch #2 then queries the display information to determine whether HDMI or DVI mode should be set. This is a v3 of the series, that addresses issues pointed out by Maxime. Changes in v3: - Move the HDMI/DVI mode set to the .atomic_enable handler (Maxime Ripard). Changes in v2: - Don't store the sink type in a per-commit bridge state (Maxime Ripard).
