drm: content-type property for HDMI connector
Added content_type property to drm_connector_state
in order to properly handle external HDMI TV content-type setting.
v2:
* Moved helper function which attaches content type property
to the drm core, as was suggested.
Removed redundant connector state initialization.
v3:
* Removed caps in drm_content_type_enum_list.
After some discussion it turned out that HDMI Spec 1.4
was wrongly assuming that IT Content(itc) bit doesn't affect
Content type states, however itc bit needs to be manupulated
as well. In order to not expose additional property for itc,
for sake of simplicity it was decided to bind those together
in same "content type" property.
v4:
* Added it_content checking in intel_digital_connector_atomic_check.
Fixed documentation for new content type enum.
v5:
* Moved patch revision's description to commit messages.
v6:
* Minor naming fix for the content type enumeration string.
v7:
* Fix parameter name for documentation and parameter alignment
in order not to get warning. Added Content Type description to
new HDMI connector properties section.
v8:
* Thrown away unneeded numbers from HDMI content-type property
description. Switch to strings desription instead of plain
definitions.
v9:
* Moved away hdmi specific content-type enum from
drm_connector_state. Content type property should probably not
be bound to any specific connector interface in
drm_connector_state.
Same probably should be done to hdmi_picture_aspect_ration enum
which is also contained in drm_connector_state. Added special
helper function to get derive hdmi specific relevant infoframe
fields.
v10:
* Added usage description to HDMI properties kernel doc.
v11:
* Created centralized function for filling HDMI AVI infoframe, based
on correspondent DRM property value.
