[PATCH v3 0/2] drm/bridge: it66121: Fix display output on DVI monitors

[Javier Martinez Canillas <javierm@redhat.com>]

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).

Javier Martinez Canillas (2):
  drm/bridge: ite-it66121: Set TX mode in the .atomic_enable callback
  drm/bridge: ite-it66121: Select HDMI or DVI mode based on sink type
