To keep this data together, further abstract the existing v4l2_rect into a partition specific structure. As partitions only have horizontal coordinates, store the left and width values only. When generating the partition windows, operate directly on the partition struct rather than copying and duplicating the processed data Signed-off-by: Kieran Bingham Reviewed-by: Laurent Pinchart --- drivers/media/platform/vsp1/vsp1_pipe.h | 15 +++++++-- drivers/media/platform/vsp1/vsp1_rpf.c | 4 +- drivers/media/platform/vsp1/vsp1_uds.c | 18 +++++----- drivers/media/platform/vsp1/vsp1_video.c | 43 +++++++++++-------------- drivers/media/platform/vsp1/vsp1_wpf.c | 14 ++++---- 5 files changed, 51 insertions(+), 43 deletions(-) diff --git a/drivers/media/platform/vsp1/vsp1_pipe.h b/drivers/media/platform/vsp1/vsp1_pipe.h index 9653ef5cfb0c..4e9fd96108be 100644 --- a/drivers/media/platform/vsp1/vsp1_pipe.h +++ b/drivers/media/platform/vsp1/vsp1_pipe.h @@ -58,6 +58,17 @@ enum vsp1_pipeline_state { };
