NAU88C22 Can't Use With NUC980

[RSTurgay]

Hi everyone,

I want to use NAU88C22YG Codec Driver. But I getting error like this,

# dmesg | grep audio
[   10.992399] nuc980-audio-i2s b0020000.i2s: obtain a copy of previously claimed pinctrl
[   11.003633] nuc980-audio ahb:sound: snd_soc_register_card() failed: -517

[   22.180774] nuc980-audio ahb:sound: snd_soc_register_card() failed: -517

My .dts file (i2c and i2s section)

i2c3: i2c3@b0083000 {
    status = "okay";
    pinctrl-0 = <&pinctrl_i2c3_PD>;

    nau8822: nau8822@1a {
        compatible = "nuvoton,nau8822";
        reg = <0x1a> ;
    };
};

i2s: i2s@b0020000 {
    status = "okay";
    pinctrl-0 = <&pinctrl_i2s_pa>;
};

i2s_pcm: i2s_pcm {
    status = "okay";
};

sound {
    compatible = "nuvoton,nuc980-audio";
    i2s-controller = <&i2s>;
    i2s-platform = <&i2s_pcm>;
    status = "okay";
};

Also, when I check nau8822 using i2cdetect, I getting address 0x1A

# i2cdetect -y 3
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

What is the point ? Where is my mistake ?

            pinctrl_i2s_pa: i2s-PA {
                nuvoton,pins =
                    <0 2 2 0
                     0 3 2 0
                     0 4 2 0
                     0 5 2 0
                     0 6 2 0 >;
            };

The error message looks like one of PA.2 ~ PA.6 had been claimed by other device. Please check your pinctrl settings.

Hi, thank you for your reply. But I check i2s pins but I din't see kernel message use another device.

It's using by i2s. Where should I check?
