I actually ran v4l2-compliance and there was problem with ADC band

Hmm, does the latest v4l2-compliance (direct from the git repo) still fail on
that? That shouldn't be a problem, and I don't see that here either if I try
that
myself.
If it still fails, can you show me the error message?

Try again, it should be fixed now.
Old error has gone, but two new comes:

That suggests you were not using the very latest media tree.
But now you'll get a new error: !(dcaps & V4L2_CAP_EXT_PIX_FORMAT)
That's because of a bug in the kernel that I mailed Laurent about.
Perhaps I was a bit too hasty in adding that to v4l2-compliance :-)
Yes, I am stuck on 3.15-rc6 media/fixes as Mauro did not apply patches
needed from fixes to master. Also, master is about always unusable as it
is very buggy rc1.
FYI: master is now rc5.
But it still not contain some critical patches needed for si2168 /
si2157 drivers, which development is very active ATM. Those patches are
only media/fixes. Every-time I need switch new kernel I need compile
whole stuff which took hour or so and reboot machine. For example
yesterday I switched ~5 times, so it is not realistic.
