* / Drivers: media: remove __dev* attributes.Greg Kroah-Hartman2013-01-03
|/ | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* [media] media: coda: set up buffers to be sized as negotiated with s_fmtPhilipp Zabel2012-09-26
| | | | | | | | | | | | | | | This fixes a failure in vb2_qbuf in user pointer mode where __qbuf_userptr checks if the buffer queued by userspace is large enough. The failure would happen if coda_queue_setup was called with empty fmt (and thus set the expected buffer size to the maximum resolution), and userspace queues buffers of smaller size - corresponding to the negotiated dimensions - were queued. Explicitly setting sizeimage to the value negotiated via s_fmt fixes the issue.

* [media] media: coda: keep track of active instancesPhilipp Zabel2012-09-26
| | | | | | | | | | | | | 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.

* [media] media: coda: ignore coda busy status in coda_job_readyPhilipp Zabel2012-09-26
| | | | | | | | | | | | | 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.

* [media] media: coda: allocate internal framebuffers separately from v4l2 buffersPhilipp Zabel2012-09-26
| | | | | | | | | | | | | | | | 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.
