+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@...5b000 {
- 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@...7c000 {
- clock-frequency = <400000>;
