### RK3588 Non-I2C MIPI CSI2 DPHY0 Device Tree Configuration Example
For configuring a non-I2C MIPI CSI2 DPHY0 interface on the RK3588 platform, it is essential to understand how device trees are structured specifically for this SoC. The configuration involves specifying properties that define the connection between the camera sensor and the processor over the MIPI CSI-2 protocol using D-PHY as the physical layer.
The following example demonstrates a typical setup within the device tree source (DTS) file:
```dts
&csi {
compatible = "rockchip,rk3588-csi";
status = "okay";
port@1 {
reg = <1>;
csi_in: endpoint {
remote-endpoint = <&camera_out>;
bus-width = <4>; /* Number of data lanes */
rockchip,mipi-dphy-lanes = <4>;
rockchip,mipi-dphy-config = <
0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10 0x11
0x12 0x13 0x14 0x15 0x16 0x17 0x18 0x19>;
};
};
};
&camera {
compatible = "vendor,sensor-name"; // Replace with actual vendor and model name.
pinctrl-names = "default";
pinctrl-0 = <&cam_pins>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
camera_out: endpoint {
remote-endpoint = <&csi_in>;
};
};
};
clock-frequency = <24000000>; // Sensor's input clock frequency in Hz.
};
```
In this snippet, `compatible` strings should be replaced according to specific hardware components used. Additionally, parameters like `bus-width`, which defines the number of data lanes utilized by the MIPI link, must match those supported both by the sensor and the system-on-chip[^1].
Device-specific settings such as power management or reset lines can also be included under the corresponding node based on requirements outlined either in datasheets provided by manufacturers or similar bindings documents found at paths mentioned previously[^3]. For instance, when dealing with sensors connected via C-PHY instead of D-PHY, adjustments will need to reflect differences in signaling characteristics[^2].
