From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx>
Some generic TV connector properties are exposed in drm_mode_config, but
they are currently handled independently in each DRM encoder driver.
Extend the drm_connector_state to store TV related states, and modify the
drm_atomic_connector_{set,get}_property() helpers to fill the connector
state accordingly.
Each driver is then responsible for checking and applying the new config
in its ->atomic_mode_{check,set}() operations.
