title: Texas Instruments DRA72x CAMERA ADAPTATION LAYER (CAL)
maintainers:
- Benoit Parrot <bparrot@ti.com>
description: |-
The Camera Adaptation Layer (CAL) is a key component for image capture
applications. The capture module provides the system interface and the
processing capability to connect CSI2 image-sensor modules to the
DRA72x device.
CAL supports 2 camera port nodes on MIPI bus.
