drm/amd/display: add ODM case when looking for first split pipe

2023-06-07T20:55:39Z

[Why] When going from ODM 2:1 single display case to max displays, second odm pipe needs to be repurposed for one of the new single displays. However, acquire_first_split_pipe() only handles MPC case and not ODM case [How] Add ODM conditions in acquire_first_split_pipe() Add commit_minimal_transition_state() in commit_streams() to handle odm 2:1 exit first, and then process new streams Handle ODM condition in commit_minimal_transition_state() Cc: Mario Limonciello Cc: Alex Deucher Cc: stable@vger.kernel.org Acked-by: Stylon Wang Signed-off-by: Samson Tam Reviewed-by: Alvin Lee Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher
