ISP Units Assignment

The tegra-isp-map node contains the mapping between the csi stream ID and ISP units. In T264, each ISP instance is assigned based on the csi stream id for the equal ISP bandwidth distribution across each camera sensor to support multiple cameras.

tegra-isp-map {
        /* Add compatible string as no parent node available */
        compatible = "nvidia,csi-isp-map-config";
        /* CSI Stream ID to ISP Instance static mapping */
        nvidia,isp-mapping =
            <0 0>,
            <1 0>,
            <2 1>,
            <3 1>,
            <4 0>,
            <5 1>;
        status = "okay";
    };

tegra-isp-map {

/* Add compatible string as no parent node available */

compatible = “nvidia,csi-isp-map-config”;

/* CSI Stream ID to ISP Instance static mapping */
