This series adds support for JPEG encoding via the VPU block
present in Rockchip platforms. Currently, support for RK3288
and RK3399 is included.
The hardware produces a Raw JPEG format (i.e. works as a
JPEG accelerator), and requires quantization tables provided
by the application.
Therefore, the series introduces a new format, and a new pair
of controls, V4L2_CID_JPEG_{LUMA,CHROMA}_QUANTIZATION
allowing userspace to specify the quantization tables.
Userspace is then responsible to add the required headers
and tables to the produced raw payload, to produce a JPEG image.
It is currently not clear if we should try to provide
a userspace helper for this kind of raw JPEG hardware,
such as a libv4l plugin, wrapping up the luma/chroma
quantization tables.
Or perhaps we can let each application (e.g. ffmpeg, gstreamer,
chrome) handle in its own way.
Roadmap
=======
This driver does not rely on the Request API, and so I believe
it could be merged as is. The next steps are support H264
and VP8 codecs.
