This patch enables decoding of h.264 and mpeg4 streams on CODA7541. Queued output buffers are immediately copied into the bitstream ringbuffer. A device_run can be scheduled whenever there is either enough compressed bitstream data, or the CODA is in stream end mode. Each successful device_run, data is read from the bitstream ringbuffer and a frame is decoded into a free internal framebuffer. Depending on reordering, a possibly previously decoded frame is marked as display frame, and at the same time the display frame from the previous run is copied out into a capture buffer by the rotator hardware. The dequeued capture buffers are counted to send the EOS signal to userspace with the last frame. When userspace sends the decoder stop command or enqueues an empty output buffer, the stream end flag is set to allow decoding the remaining frames in the bitstream ringbuffer. The enum_fmt/try_fmt functions return fixed capture buffer sizes while the output queue is streaming, to allow better autonegotiation in userspace. A per-context buffer mutex is used to lock the picture run against buffer dequeueing: if a job gets queued, then streamoff dequeues the last buffer, and then device_run is called, bail out. For that the interrupt handler has to be threaded. Signed-off-by:

Add coda_prepare_encode() and coda_finish_encode() functions. They are called from coda_device_run() and coda_irq_handler(), respectively, before and after the hardware picture run. This should make the following decoder support patch easier to read, which will add the coda_prepare/finish_decode() equivalents. Signed-off-by:

The lirc interface allows 255 u32 spaces and pulses, which are usec. If the driver can handle this (e.g. winbond-cir) you can produce hours of meaningless IR data and there is no method of interrupting it. Signed-off-by:

This commit adds an early check to vidioc_s_std() to detect if the new and current standards are equal, and exit with success in that case. This is needed to prevent userspace applications that might attempt to re-set the same standard from failing if that's done when streaming has started. Signed-off-by:

Remove the check as there's no reason to prevent the input from being set when the device is streaming. This allows surveillance applications (such as motion, zoneminder, etc.) to configure the input while streaming. Reported-by:

check_firmware() makes sure firmware is in a device. It returns zero on success and error code otherwise. Also it sets down_firmware flag to 1 if downloading occurs. The only caller poseidon_probe() checks down_firmware flag and returns 0 without any initialization if it is set. That looks very strange, so the patch removes down_firmware argument of check_firmware() and returns error code if check_firmware() fails in poseidon_probe(). Not tested on real hardware.
