I have a schematic in my master thesis, which shows how the camera
sensors are connected to the SoC. The PDF is available here:
https://www.uni-oldenburg.de/fileadmin/user_upload/informatik/ag/svs/download/thesis/Reichel_Sebastian.pdf
The schematic is on page 37 (or 45 if your PDF reader does not
use different numbers for the preamble stuff).
