Good point.
IMO, it is a little premature to drop those. I mean, clearly at least
some firmware for the ISP2 is capable of encoding in JPEG format,
but the code which creates such pipeline is not selecting the right
binary.
Btw, the same issue also happens here for BG10 fourcc, which is the
real output of the sensor:
$ v4l2grab -f BG10 -x 1600 -y 1200 -d /dev/video2 -u -n 1 -R
Device caps: CAPTURE OUTPUT STREAMING EXT_PIX_FORMAT DEVICE_CAPS STREAMING
Driver caps: CAPTURE OUTPUT STREAMING EXT_PIX_FORMAT STREAMING
xioctl(5): error 22, Invalid argument

See, basically the logic which seeks for a firmware that would allow
to just copy the MBUS format without touching it failed somewhere.
As no binary should be required to convert from BG10, as this is the
native format, I strongly suspect that the logic which sets the pipeline
has some bug.
So, I wouldn't drop support for Bayer and JPEG for now. Instead, the
best seems to comment out the broken stuff for now, while we're dealing
with more relevant issues. We can return later on to address such
formats.

Mauro
