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
- 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 {
compatible = "ovti,ov5640";
reg = <0x3c>;
clocks = <&clk_fixed>;
clock-names = "xclk";
port {
csi2_cam0: endpoint {
remote-endpoint = <&csi2_phy0>;
clock-lanes = <0>;
data-lanes = <1 2>;
};
};
};
};
