+Texas Instruments DRA72x CAMERA ADAPTATION LAYER (CAL)
+------------------------------------------------------
+
+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.
+
+Required properties:
+- compatible: must be "ti,cal"
+- reg: physical base address and length of the registers set for the 4
+       memory regions required;
+- reg-names: name associated with the memory regions described is <reg>;
+- interrupts: should contain IRQ line for the CAL;
+
+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.
+
+Example:
+       cal: cal@4845b000 {
+               compatible = "ti,cal";
+               ti,hwmods = "cal";
+               reg = <0x4845B000 0x400>,
+                     <0x4845B800 0x40>,
+                     <0x4845B900 0x40>,
+                     <0x4A002e94 0x4>;
