Guennadi,
I thought a bit about pixel format negociation.
The thing that came to my mind is that it is not the sensor that can tell all
the pixel formats available, it's the camera host. That means that icd->formats
should be filled in by the host, not the sensor.
What I would see is a generic call in soc_camera (or a structure), called by
each sensor to declare the pixel formats it handles. This call (or structure)
will be used by camera host driver to fill in icd->formats, deduced from what
the sensors offers, and the host possible translations.
Tell me you opinion about it please.
