Aligning capture queue image dimensions while enqueuing output
queue doesn't make a sense as the S_FMT ioctl might have not
been called for the capture queue until that moment, whereas
it is required to know capture format as the type of alignment
heavily depends on it.

Exynos4x12 has limitations regarding setting chroma subsampling
of an output JPEG image. It cannot be lower than the subsampling
of the raw source image. Also in case of V4L2_JPEG_CHROMA_SUBSAMPLING_GRAY
option the source image fourcc has to be V4L2_PIX_FMT_GREY.

Adjust capture format to the Exynos4x12 device limitations,
according to the subsampling value parsed from the source
JPEG image header. If the capture format was set to YUV with
subsampling lower than the one of the source JPEG image
the decoding process would not succeed.

Hi Valentine,
I don't entirely understand how you use this driver with soc-camera.
Since soc-camera doesn't support FMT_CHANGE notifies it can't really
act on it. Did you hack soc-camera to do this?
The way it stands I would prefer to see a version of the driver without
soc-camera support. I woul
Just a quick update:
I've been working on this for the past four days and I am now in the process
of testing this. Adding matrix support to the control framework was actually
the hardest part, particularly since I wanted it to be efficient. The code is
still a bit too complex for my liking, but on
