2012-08-15[media] rename drivers/media/video as .../platformMauro Carvalho Chehab
The remaining drivers are mostly platform drivers. Name the dir to reflect it. It makes sense to latter break it into a few other dirs. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-05-20[media] v4l: s5p-tv: Fix section mismatch warning in mixer_video.cSachin Kamat

2011-09-06[media] media: vb2: change queue initialization orderMarek Szyprowski
This patch changes the order of operations during stream on call. Now the buffers are first queued to the driver and then the start_streaming method is called. This resolves the most common case when the driver needs to know buffer addresses to enable dma engine and start streaming. Additional parameter to start_streaming method have been added to simplify drivers code. The driver are now obliged to check if the number of queued buffers is high enough to enable hardware streaming. If not - it can return an error. In such case all the buffers that have been pre-queued are invalidated. This patch also updates all videobuf2 clients to work properly with the changed order of operations.
