That would be nice!

As far as I know the drivers are already available in the hw-validation
kernel and I have added some preliminary entries to the board file but did not
look into controlling everything. We man need 2 or 3 additional pins to be
configured as GPIOs to reset and enable the camera. And of course switch on
the 2.5V power.

This may be a good start to read (preliminary datasheet of the camera chip):

The data sheet of the camera module itself describes more the mechanical
parts of the module and the pin layout of the FFC.
