As for CCD-information you should find something on data-sheets of the
cpia-chip available on the STM webpage (www.st.com). As for
lens-information I think this is specific to the actual camera model
you bought. That should be the thing the cameras from the various
vendors differ. So you would have to contact the vendor of your camera.

Bug. Which driver version is this?

This is userland stuff. I don't really know where the linux-community
gathers to discuss such stuff. :)
