That's great news. Then I might not need to do all the work on my own;)

All right, there is no rush. I was just looking around how to support the
camera scene mode with m5mols sort of sensors. The scene mode is essentially
a compilation of several different parameters, for some of which there are
standard controls in V4L2 but for many there are not.

I've got a feeling the best way to handle this would be to create controls
for each single parameter and then do a batch set from user space, and keep
the scene mode mappings in user space. The only concern is there is a couple
of ISP-specific parameters involved with that scene mode thing. Perhaps they
just could be set initially to fixed values.
