The DSS supports one each of video pipeline (vid) and video-lite pipeline (vidl1). The video port 1 (vp1) is tied-off in AM62A SoC, but the pipeline remains active. The video port 2 (vp2) outputs the DPI signals. Both the video ports are connected to the pipelines via 2 identical overlay managers (ovr1 and ovr2).
