title: Texas Instruments DRA72x CAMERA ADAPTATION LAYER (CAL) Device Tree Bindings
maintainers:

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. Each CSI2 camera port nodes
should contain a 'port' child node with child 'endpoint' node. Please
refer to the bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt.
