Userspace has a hard time making sense of format enumerations on V4L2 mem2mem devices if there are restrictions on which input and output formats can be used together. Alleviate the problem by splitting the video4linux device into separate encoder and decoder devices which list only raw formats on one side and only encoded formats on the other side. With this patch, the instance type (encoder or decoder) is already determined by the open file operation.

This patch exports all auxiliary buffers, including SRAM, as debugfs binary blobs for debugging purposes. It shows, for example, that psbuf currently doesn't seem to be used at all on CODA7541, and that slicebuf and workbuf usage is far from the maximum. It can also be used to validate SRAM size allocation.

When encoding into h.264, the input frame stride needs to be a multiple of 16. During allocation of the input buffers, it may not be known yet whether the encoder should create h.264 or not.

Even though the CODA h.264 decoder always decodes complete macroblocks, we can set the stride to the corresponding multiple of 16 and use a value smaller than that as real width. Unfortunately the same doesn't work for height, as there is no vertical linesperframe stride for discontiguous planar YUV frames.

Rename the per-context prescan_failed variable to hold, as this is what the flag does: it temporarily keeps the coda from running until new data is fed into the bitstream buffer or stop_streaming is called on the input side.

The coda h.264 decoder also counts PIC_RUNs where no frame was decoded but a frame was rotated out / marked as ready to be displayed. This causes an offset between the incoming encoded frame's sequence number and the decode sequence number returned by the coda.

The coda driver advertises timestamp_type V4L2_BUF_FLAG_TIMESTAMP_COPY on both queues, so we have to copy timestamps from input v4l2 buffers to the corresponding destination v4l2 buffers.

Using the coda_mutex lock to serialize hardware access would cause "INFO: possible circular locking dependency detected" lockdep warnings. Since the possible locking paths are hard to follow, serialize hardware access with a single workqueue thread. Ultimately the workqueue could be converted to only do register setup and readout for per-command work items. Using the initialized context property, SEQ_END is only queued in coda_release when needed.
