   13   The Camera Adaptation Layer (CAL) is a key component for image capture
   14   applications. The capture module provides the system interface and the
   15   processing capability to connect CSI2 image-sensor modules to the
   16   DRA72x device.
   17 
   18   CAL supports 2 camera port nodes on MIPI bus.
