How to use multi adau1761 with axi i2s adi ip

I am using the ADAU1761 audio codec on my system with the Analog Devices AXI I2S ADI IP. I have successfully validated and run the system for one ADAU1761 using the following device tree on PetaLinux 2019.2:

/include/ "system-conf.dtsi"
/ {
    fpga_axi: fpga-axi@0 {
        compatible = "simple-bus";
        #address-cells = <0x1>;
        #size-cells = <0x1>;
        ranges;

        audio_clock: audio_clock {
            compatible = "fixed-clock";
            #clock-cells = <0>;
            clock-frequency = <12288000>;
        };

        zed_sound {
            compatible = "simple-audio-card";
            simple-audio-card,name = "ZED ADAU1761";
            simple-audio-card,widgets =
                "Microphone", "Mic In",
                "Headphone", "Headphone Out",
                "Line", "Line In",
                "Line", "Line Out";
            simple-audio-card,routing =
                "Line Out", "LOUT",
                "Line Out", "ROUT",
                "Headphone Out", "LHP",
                "Headphone Out", "RHP",
                "Mic In", "MICBIAS",
                "LINN", "Mic In",
                "RINN", "Mic In",
                "LAUX", "Line In",
                "RAUX", "Line In";

            simple-audio-card,dai-link@0 {
                format = "i2s";
                cpu {
                    sound-dai = <&axi_i2s_adi_0>;
                };
                codec {
                    sound-dai = <&adau1761>;
                };
            };
        };
    };
};

&i2c0 {
    status = "okay";
    compatible = "xlnx,xps-iic-2.00.a";
    reg = <0x41600000 0x10000>;
    interrupt-parent = <&intc>;
    interrupts = <0 30 4>;
    clocks = <&clkc 15>;
    clock-names = "pclk"; 
    #size-cells = <0>;
    #address-cells = <1>; 
    adau1761: adau1761@3b {
        #sound-dai-cells = <0>;   // only single DAI
        compatible = "adi,adau1761";
        reg = <0x3b>;
        clocks = <&misc_clk_0>;
        clock-names = "mclk";
    };
};

&axi_i2s_adi_0 {
    #sound-dai-cells = <0>;            
    compatible = "adi,axi-i2s-1.00.a";
    dmas = <&dmac_s 1 &dmac_s 2>;
    dma-names = "tx", "rx";
    clocks = <&clkc 15>, <&audio_clock>;
    clock-names = "axi", "ref";
    reg = <0x77600000 0x10000>;
    xlnx,bclk-pol = <0x0>;
    xlnx,dma-type = <0x1>;
    xlnx,has-rx = <0x1>;
    xlnx,has-tx = <0x1>;
    xlnx,lrclk-pol = <0x0>;
    xlnx,num-ch = <0x1>;
    xlnx,slot-width = <0x18>;
};

Also you can see my block design below for two adau1761(i could not run this with proper device tree);

Actually my goal is that i want to use 8 ADAU1761 chips in the system. How should I modify the device tree when I increase the number of channels by updating xlnx,num-ch = <0x1>; for the AXI I2S ADI, to accommodate this configuration?

Could you give me an example?

Thanks ,
