Hi,
These patches add JPEG encoding and decoding support for CODA7541 (i.MX5).
The encoder video device is split into one video device per codec, so that
each video device can register only the relevant controls. The H.264/MPEG4
decoder is kept as one video device, but the JPEG decoder video device is
separate because it supports more uncompressed formats (currently YUV422P,
in the future grayscale or YUV 4:4:4 support could be added).
regards
Philipp
