ISP Units Assignment

The tegra-isp-map node contains the mapping between the sensor ID and ISP units. In T264, each ISP instance is assigned based on the sensor ID to achieve balanced ISP bandwidth distribution across multiple camera sensors.

tegra-isp-map {
        /* Add compatible string as no parent node available */
        compatible = "nvidia,sensor-isp-map-config";
        /* Sensor ID to ISP Instance static mapping */
        nvidia,isp-mapping =
            <0 0>,
            <1 1>,
            <2 0>,
            <3 1>,
            <4 0>,
            <5 1>,
            <6 0>,
            <7 1>,
            <8 0>,
            <9 1>,
            <10 0>,
            <11 1>,
            <12 0>,
