How to add Codec DA7213 in RZG2L-SMARC-EVK WS1

Hi,

I am working on Codec DA7213 interface with RZG2L-SMARC-EVK WS1 board.

I have Codec DA7213 EVK board, where I can access I2C and I2S lines.

I disable the WM8978 codec present in RZG2L-SMARC-EVK WS1 and added DA723 details in rzg2l-smarc.dtsi file.

Also change the SSI0 channel to SSI1 because SSI1 is available on PMOD connector.

I am using I2C3 channel form Pin 3 and 4 of PMOD1 and I2S channel form Pin 4,3,2,1 of PMOD0.

Please find below changes done in rzg2l-smarc.dtsi file.

1. Added snd_rzg2l:sound

2. Added DA7213 in I2C3

3. Select Pins for SSI1.

4. Remove RSPI1, because of pin conflict.

    snd_rzg2l: sound {
        compatible = "simple-audio-card";
        simple-audio-card,format = "i2s";
        simple-audio-card,bitclock-master = <&cpu_dai>;
        simple-audio-card,frame-master = <&cpu_dai>;
        
        simple-audio-card,widgets =

        simple-audio-card,routing =

            "MIC2", "Mic Bias",

            "Headphone Jack", "HPR",
            "Speaker Out", "LINE";
        cpu_dai: simple-audio-card,cpu {

        };

        codec_dai: simple-audio-card,codec {
            sound-dai = <&da7213>;
            clocks = <&versa3 0>;
        };
    };

    sound_card {
        compatible = "audio-graph-card";
        dais = <&ssi0>;
    };

&i2c3 {

    status = "okay";

    versa3: versa3@68 {

        clock-flags = <2176>, <2176>, <2176>, <2052>, <2176>, <2048>;
    };
    
    da7213: da7213@1a {

        reg = <0x1a>;
        dlg,micbias1-lvl = <2500>;
        dlg,micbias2-lvl = <2500>;

        dlg,dmic-samplephase = "between_clkedge";
        dlg,dmic-clkrate = <3000000>;
    };

    wm8978: codec@1a {
        compatible = "wlf,wm8978";
        #sound-dai-cells = <0>;
        reg = <0x1a>;
        status = "disabled";
    };
};

    ssi1_pins: ssi1 {
        groups = "ssi1_ctrl_c", "ssi1_data_c";
        function = "ssi1";
    };

    /*spi1_pins: rspi1 {
        groups = "rspi1_clk_b", "rspi1_data_b", "rspi1_ssl_b";
        function = "rspi1";
    };*/

Also I made change in defconfig as follows

CONFIG_SND_SOC_WM8978=n
CONFIG_SND_SOC_DA7213=y

After that i use bitbake linux-renesas -fc compile and  bitbake linux-renesas -fc deploy commands to compile it.

Can you please guide us on the same.

How I will conform that, This DA7213 is added or not??

What I have done is correct or any thing I gave to do??

Thanks & Regards
