Commit 731514b446fe6748d5a55a3dff202efb45c7d8df upstream.
|
|
|
|
|
Reworked as functions have been moved from drm_atomic_helper.[c|h]
|
|
|
|
|
to drm_atomic_state_helper.[c|h].
|
|
|
|
|
|
|
|
|
|
During the connector reset, if that connector has a TV property, it needs
|
|
|
|
|
to be reset to the value provided on the command line.
|
|
|
|
|
|
|
|
|
|
Provide a helper to do that.
