[PATCH v5 00/10] add aspeed-jpeg support for aspeed-video

[Hans Verkuil]

Hi Jammy,

I suggest posting a v3 that moves the patches that deal with the
Aspeed JPEG format to the end of the series. That way I can easily
merge the patches up to that point, and the Aspeed JPEG support can
be handled separately.

I'm not sure if it can be merged without that format being documented,
either in pixfmt-reserved.rst, by implementing support for it in
libv4lconvert from v4l-utils, or by providing a URL to some other
publicly available source code. We really don't like adding pixel
formats that cannot be interpreted by someone without access to the
datasheets.

Regards,

	Hans
