The first two patches simplify the function to find buffers based on a timestamp: the current code only considered DONE and DEQUEUED buffers, but that is unnecessarily restrictive. The next two patches keep dmabuf-based buffers mapped when they are dequeued. This avoids having to re-map them if they are referenced as key frames in a stateless codec. This patch has been in use by ChromeOS for quite some time and it makes sense. It is more efficient in general anyway since you don't want to have to map a dmabuf every time you queue it if there is no need for it. The next 5 patches fix v4l2-compliance bugs in vivid and vimc for output field handling in requests. The final patch fixes a vivid buf_prepare bug.
