I am not offended at all, I certainly agree with Pavel's opinion of 'do
not invent new interfaces needlessly'. But this is a use case significantly
different from what the v4l2 api is aimed at.

As I wrote earlier, if it were not for other reasons, then changing the
API is not an option because the software already ships. I can place the
driver somewhere else in the kernel tree. I can fix any issues that
someone may find with it. I certainly cannot replace it with something
entirely different. If it is rejected, my only option is to submit the
rest of the code, without the capturing driver (the platform is already
in the kernel tree). Some may feel that a camera that cannot capture
images is somewhat pointless, though...

Of course, everyone is free to write a v4l2 driver, but will likely
find that the hardware is not very suitable as a streaming video
device. At least, it would be a very expensive one...
