Hi Tomi,
I'm very happy to see this being worked on again!
Is there code somewhere that demonstrates the v5 API in use? I still
have old branches of this series and it would be nice to see how the API
have evolved for drivers.
Likewise are there some user-space code around that can be used to test
the API? For v2 and v3 I had some hack patches [1], do they still work?
More likely they have gone stale by now :-)

Yes for both. I didn't share those as they're not in a presentable state =).
But, with the disclaimer that your eyes may bleed when reading the code:
git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git
multistream/work
git://github.com/tomba/kmsxx.git multistream
On the kernel side, the CAL driver is in relatively good shape. UB960
driver is somewhat messy but not totally horrible. OV10635 is horrible,
as it's used to fake metadata stream even if the sensor doesn't really
have such a thing.
For testing I have used kms++ with python bindings. My test script is
py/tests/cam.py
The uAPI has changed as there's now the 'which' field. But I think
that's the only clear change, although the behavior could be slightly
different wrt. setting formats.
