Hello, This patch series replaces the media graph walk API usage in several drivers with iteration over entities or pads stored in the media_pipeline object. Iteration over the constructed pipeline is more efficient, and will support the V4L2 stream API correctly. Patches 1/5 and 2/5 start by adding two macros to iterate over pads and entities in a pipeline. Patch 2/5 also marks the media graph walk API as deprecated as a result. Patches 3/5 to 5/5 then use the new iterators in three drivers (omap3isp, omap4iss and xilinx). Compared to v2, this version fixes compilation errors in the omap3isp and omap4iss drivers (no idea how those crept in, I would have sworn I had compile-tested everything). With this series applied, only two drivers still use the media graph walk API: exynos4-is and vsp1. Those are more difficult to address. I plan to work on the vsp1 driver, but not on exynos4-is as I miss knowledge of the code base and have no hardware to test changes on. As with v1, volunteers would be appreciated :-) Laurent Pinchart (5): media: mc: entity: Add pad iterator for media_pipeline media: mc: entity: Add entity iterator for media_pipeline media: ti: omap3isp: Use media_pipeline_for_each_entity() media: ti: omap4iss: Use media_pipeline_for_each_entity() media: xilinx: dma: Use media_pipeline_for_each_pad() drivers/media/mc/mc-entity.c | 55 +++++++++++ drivers/media/platform/ti/omap3isp/ispvideo.c | 20 ++-- drivers/media/platform/xilinx/xilinx-dma.c | 28 ++---- drivers/staging/media/omap4iss/iss_video.c | 66 +++++-------- include/media/media-entity.h | 98 +++++++++++++++++++ 5 files changed, 192 insertions(+), 75 deletions(-) base-commit: d4acfa22b634347be33d5906744366742fccd151 -- Regards, Laurent Pinchart
