text: Camera sensors are connected directly to Nomadik 1.5, which has embedded image pre-processing block.
  Electrical interface consists of Nomadik 1.5 IPI2C for controlling camera module, a CCP2 interface for camera
  data (Main camera using CCP0. secondary camera CCP1), camera clock (ExtClk) and CAM0_SD / CAM1_SD data
  (Main camera / secondary camera) signal made by GPIO-pin for controlling camera shutdown. Camera is
  powered by Touareg1bis VIO SMPS (1.8V) and discrete linear regulator (2.8V). Main camera is 5MP Stingray;
  secondary camera is Acme lite (VGA). Camera system includes led flash with flash driver and indicator led.
  Flash driver and indicator led get control data through I2C from Nomadik. Two GPIO-pins are needed for
  enabling flash driver and flash timing strobe.
