Subject: [PATCH] drm: Add TV connector states to drm_connector_state
|
|
|
|
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.
