2016-09-19[media] v4l: vsp1: Disable VYUY on Gen3Laurent Pinchart
The VYUY format isn't supported on Gen3 hardware, disable it. Gen2 hardware supports VYUY in practice even though the documentation doesn't advertise it, so keep it for Gen2 devices.

2016-09-19[media] v4l: vsp1: Support multiple partitions per frameKieran Bingham
Adapt vsp1_video_pipeline_run() such that it can iterate each partition required for constructing this frame's display list chain in the event that multiple display lists are required to process in hardware. The first display list is held as the head list object, whilst any following parition display lists are linked to the head by means of vsp1_dl_list_add_chain(). Linking the chained display list headers to process using the auto start mechanism of the hardware is performed during the vsp1_dl_list_commit().

2016-09-19[media] v4l: vsp1: Determine partition requirements for scaled imagesKieran Bingham
The partition algorithm needs to determine the capabilities of each entity in the pipeline to identify the correct maximum partition width. Extend the vsp1 entity operations to provide a max_width operation and use this call to calculate the number of partitions that will be processed by the algorithm. Gen 2 hardware does not require multiple partitioning, and as such will always return a single partition.

2016-06-28[media] v4l: vsp1: Simplify alpha propagationLaurent Pinchart
We don't need to walk the pipeline when propagating the alpha value as all the information needed for propagation is already available from the pipeline structure.

2016-06-28[media] v4l: vsp1: pipe: Fix typo in commentLaurent Pinchart
The vsp1_pipeline wq field is a wait queue, not a work queue. Fix the comment accordingly. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-17[media] v4l: vsp1: Move frame sequence number from video node to pipelineLaurent Pinchart
The frame sequence number is global to the pipeline, there's no need to store copies in each video node. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-04-13[media] v4l: vsp1: Allocate pipelines on demandLaurent Pinchart
Instead of embedding pipelines in the vsp1_video objects allocate them on demand when they are needed. This fixes the streamon race condition where pipelines objects from different video nodes could be used for the same pipeline.

This prepares for dynamic pipeline allocation by providing a field that can be used to store the pipeline pointer atomically under driver control. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-04-13[media] v4l: vsp1: Pass display list explicitly to configure functionsLaurent Pinchart
Modules write register values to the active display list pointed to by the pipeline. In order to support preparing display lists ahead of time, pass them explicitly to all configuration functions.

2016-02-19[media] v4l: vsp1: Add display list supportTakashi Saito
Display lists contain lists of registers and associated values to be applied atomically by the hardware. They lower the pressure on interrupt processing delays when reprogramming the device as settings can be prepared well in advance and queued to the hardware without waiting for the end of the current frame. Display list support is currently limited to the DRM pipeline.

2016-02-19[media] v4l: vsp1: Make pipeline inputs array index by RPF indexLaurent Pinchart
The pipeline inputs array stores pointers to all RPFs contained in the pipeline. It's currently indexed contiguously by adding RPFs in the order they are found during graph walk. This can't easily support dynamic addition and removal of RPFs while streaming, which will be required for combined VSP+DU support. Make the array indexed by RPF index instead and skip NULL elements when iterating over RPFs.
