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,dra72-cal"
- 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;
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";
ti,hwmods = "cal";
reg = <0x4845B000 0x400>,
<0x4845B800 0x40>,
<0x4845B900 0x40>,
<0x4A002e94 0x4>;
reg-names = "cal_top",
"cal_rx_core0",
"cal_rx_core1",
"camerrx_control";
interrupts = <GIC_SPI 119 IRQ_TYPE_LEVEL_HIGH>;
#address-cells = <1>;
#size-cells = <0>;
ports {
#address-cells = <1>;
#size-cells = <0>;
csi2_0: port@0 {
reg = <0>;
endpoint {
slave-mode;
remote-endpoint = <&ar0330_1>;
};
};
csi2_1: port@1 {
reg = <1>;
};
};
};
i2c5: i2c@4807c000 {
ar0330@10 {
compatible = "ti,ar0330";
reg = <0x10>;
port {
#address-cells = <1>;
#size-cells = <0>;
ar0330_1: endpoint {
reg = <0>;
clock-lanes = <1>;
data-lanes = <0 2 3 4>;
remote-endpoint = <&csi2_0>;
};
};
};
};
