Reset sequence for MFC V7 and V8 do not need RISC_ON to be set to 0, while for MFC V6 it is still needed. Also, remove a couple of register settings during Reset which are not needed from V6 onwards.

Timestamp i of a previously decoded buffer was overwritten for some H.264 streams with timestamp i+1 of the next buffer. This happened when encountering frame_type S5P_FIMV_DECODE_FRAME_SKIPPED, indicating no new frame. In most cases this wrong indexing might not have been noticed except for a one frame delay in frame presentation. For H.264 streams though that require reordering of frames for presentation, it caused a slightly erratic presentation time lookup and consequently dropped frames in the Pepper Flash plugin.

The enter_suspend flag is set after we enter mfc suspend function but if suspend fails after that due to any reason (like hardware timeout etc), this flag must be cleared before returning an error. Otherwise, this flag never gets cleared and the MFC suspend will always return an error on subsequent tries. If clock off fails, disable hw_lock also.

This patch adds a quick check for valid JPEG frames before feeding them into the bitstream buffer: Frames that do not begin with the JPEG start of image marker and end with the end of image marker are dropped.

For small frame sizes, allocating 1 MiB per compressed buffer is a waste of space. On the other hand, incompressible 1080p data can produce JPEGs larger than 1 MiB at higher quality settings. Allow userspace to set the compressed buffer size and clamp the value to a sensible range. Also set the initial sizeimage to a value inside the range allowed by try_fmt. While at it, reduce the default image size to a maximum of 1920*1088 (otherwise JPEG will default to 8k*8k and 96 MiB buffers).

With bitstream padding, it is possible to decode a single JPEG in the bitstream immediately. This allows us to only ever queue a single JPEG into the bitstream buffer, except to increase payload over 512 bytes or to back out of hold state. This is a measure to decrease JPEG decoder latency.

Storing the buffer position in the bitstream with the buffer metadata allows to later use that information to drop metadata for skipped buffers and to determine whether bitstream padding has to be applied. This patch also renames struct coda_timestamp to struct coda_buffer_meta to make clear that it contains more than only the buffer timestamp.

This patch adds JPEG encoding and decoding support for CODA7541, using the BIT processor. Separate JPEG encoder and decoder video devices are created due to different streaming behaviour and different supported pixel formats. The hardware can not change subsampling on the fly, but encode and decode 4:2:2 subsampled JPEG images from and into this format. The CODA7541 JPEG decoder uses the bitstream buffer and thus can run without new buffers queued if there is a buffer in the bitstream. Since there is no standard way to store the colorspace used in JPEGs, and to make v4l2-compliance happy, the JPEG format always reports V4L2_COLORSPACE_JPEG.

Each video device descriptor determines the name, callback ops, and input and output formats on the corresponding video device. This simplifies coda_enum_fmt and coda_try_fmt a bit and will simplify adding separate video devices for JPEG codecs due to the slightly different behavior in the CodaDx6/CODA7542 case and a separate hardware unit on CODA960.

smiapp_set_format() has accumulated a fair amount of changes without a needed refactoring, do the cleanup now. There's also an unlocked version of v4l2_ctrl_range_changed(), using that fixes a small serialisation issue with the user space interface. __v4l2_ctrl_modify_range() is used instead of v4l2_ctrl_modify_range() in smiapp_set_format_source() since the mutex is now held during the function call.
