2012-09-26[media] media: coda: keep track of active instancesPhilipp Zabel1-4/+17
Determining the next free instance just by incrementing and decrementing an instance counter does not work: if there are two instances opened, 0 and 1, and instance 0 is released, the next call to coda_open will create a new instance with index 1, but instance 1 is already in use. Instead, scan a bitfield of active instances to determine the first free instance index.

2012-09-26[media] media: coda: ignore coda busy status in coda_job_readyPhilipp Zabel1-6/+0
job_ready is supposed to signal whether a context is ready to be added to the job queue, not whether the CODA is ready to run it immediately. Calling v4l2_m2m_job_finish at the end of coda_irq_handler already guarantees that the coda is ready when v4l2-mem2mem eventually tries to run the next queued job.

2012-09-26[media] media: coda: allocate internal framebuffers separately from v4l2 buffersPhilipp Zabel1-55/+86
Some codecs running on CODA need internal framebuffers for reference and reconstructed frames. Allocate them separately, and do not use the input vb2_buffers: those will be handed off to userspace regularly, and there is no way to signal to the CODA which of the registered framebuffers are off limits. As a consequence, userspace is now free to choose the number of v4l2 buffers. This patch also includes the code to set up the parameter buffer for CODA7 and above with 64-bit AXI bus width.

2012-09-26[media] v4l2-core: tvnorms may be 0 for a given input, handle that caseHans Verkuil2-2/+7
Currently the core code looks at tvnorms to see whether ENUMSTD or G_PARM should be enabled. This is not a good check for drivers that support the STD API on one input and the DV Timings API on another. In that case tvnorms may be 0. Instead check whether s_std is present (for ENUMSTD) or whether g_std or current_norm is present for g_parm. Also, in the enumstd core function return ENODATA if tvnorms is 0, because in that case the current input does not support the STD API and ENUMSTD should return ENODATA for that.
