12description: |-
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.
