I think I added the pinctrl-name and pinctrl id in its example, to
make it easier for the user to understand , like below, what do you
think? thanks
examples:

    sound: mt8186-sound {
        compatible = "mediatek,mt8186-mt6366-rt1019-rt5682s-sound";
        mediatek,platform = <&afe>;
        pinctrl-names = "aud_clk_mosi_off",
                        "aud_clk_mosi_on";
+                       "aud_gpio_dmic_sec";
        pinctrl-0 = <&aud_clk_mosi_off>;
        pinctrl-1 = <&aud_clk_mosi_on>;
+       pinctrl-2 = <&aud_gpio_dmic_sec>;

+       dmic-gpios = <&pio 23 GPIO_ACTIVE_HIGH>;

        headset-codec {
            sound-dai = <&rt5682s>;
        };

        playback-codecs {
             sound-dai = <&it6505dptx>,
                         <&rt1019p>;
        };
    };
