With synchronous subdevice probing regulators should be requested by the
soc-camera core in soc_camera_pdrv_probe(). Subdevice drivers, supporting
asynchronous probing, call soc_camera_power_init() to request regulators.
Erroneously, the same regulator array is used in the latter case as in
the former, which leads to a failure. This patch fixes it by preventing
the second regulator request from being executed.

Each source entity maintains a pointer to the counterpart sink
entity while an enabled link connects them. It should be managed by
the setup_link callback in the media controller framework at runtime.

This registers the pointer to a sink entity from the source entity

The VSP1 is a video processing engine that includes a blender, scalers,
filters and statistics computation. Configurable data path routing logic
allows ordering the internal blocks in a flexible way.
Due to the configurable nature of the pipeline the driver implements the
media controller API and doesn't use the V4L2 mem-to-mem framework, even
though the device usually operates in memory to memory mode.
Only the read pixel formatters, up/down scalers, write pixel formatters
and LCDC interface are supported at this stage.

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.
