+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.

-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:
- Should be "ti,dra72-cal", for DRA72 controllers
- Should be "ti,dra72-pre-es2-cal", for DRA72 controllers pre ES2.0
- Should be "ti,dra76-cal", for DRA76 controllers
- Should be "ti,am654-cal", for AM654 controllers
-- reg:	CAL Top level, Receiver Core #0, Receiver Core #1 and Camera RX
-	control address space
-- reg-names: cal_top, cal_rx_core0, cal_rx_core1 and camerrx_control
-	     registers
-- interrupts: should contain IRQ line for the CAL;
-- ti,camerrx-control: phandle to the device control module and offset to
-		      the control_camerarx_core register.
-		      This node is meant to replace the "camerrx_control"
-		      reg entry above but "camerrx_control" is still
-		      handled for backward compatibility.
-
-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,dra72-cal";
-		reg = <0x4845B000 0x400>,
-		      <0x4845B800 0x40>,
-		      <0x4845B900 0x40>;
-		reg-names = "cal_top",
-			    "cal_rx_core0",
-			    "cal_rx_core1";
-		interrupts = <GIC_SPI 119 IRQ_TYPE_LEVEL_HIGH>;
-		ti,camerrx-control = <&scm_conf 0xE94>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		ports {
-			#address-cells = <1>;
-			#size-cells = <0>;
-
-			csi2_0: port@0 {
-				reg = <0>;
-				csi2_phy0: endpoint {
-					remote-endpoint = <&csi2_cam0>;
-					clock-lanes = <0>;
-					data-lanes = <1 2>;
-				};
-			};
-			csi2_1: port@1 {
-				reg = <1>;
-			};
-		};
-	};
-
-	i2c5: i2c@4807c000 {
-		clock-frequency = <400000>;
-
-		camera-sensor@3c {
