Thanks for your reply!
I now got it working, at least as far as camss is concerned. I can
confirm the camss driver is working for 4 lanes, and that the DTS
settings described above are correct.
Some of the problems I had were related to the sensor driver reporting
wrong clock values, which in turn caused camss to not configure its
hardware clocks correctly.
Linux userspace does not seem to be prepared for Bayer 10bit packed
formats at all however, but that's out of scope for this list I guess.
Thanks again!
Daniel
