=== Device tree configuration ===
Here below an example of device tree configuration used on standard DAVE's kit for the ORCA SOM:
From <code>imx8mp-mito8mplus-cb1001.dts</code>:

port@0 {
reg = <0>;
mipi_csi0_ep: endpoint {
remote-endpoint = <&ov5640_mipi_0_ep>;
data-lanes = <2>;
csis-hs-settle = <13>;
csis-clk-settle = <2>;
csis-wclk;
};
};
};
&mipi_csi_1 {
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
port@1 {
reg = <1>;
mipi_csi1_ep: endpoint {
remote-endpoint = <&ov5640_mipi_1_ep>;
data-lanes = <2>;
csis-hs-settle = <13>;
csis-clk-settle = <2>;
csis-wclk;
};
};
};
</pre>
From <code>imx8mp-mito8mplus.dtsi</code>:
<pre>
&iomuxc {

fsl,pins = <
