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 ,
