12 description: |-
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.
