Missing vendor prefix. You got comments for it already.

Why you do not use DAI links for all these?

Drop blank line.

Drop label, not used. Use generic node names, so just "sound".

Hi Krzysztof,

I will correct it in V4.

Are the following examples "DAI links" you mean?

hdmi-dai-link {
            link-name = "HDMI Playback";
            cpu {
                sound-dai = <&q6afedai TERTIARY_MI2S_RX>;
            };

            platform {
                sound-dai = <&q6routing>;
            };

            codec {
                sound-dai = <&lt9611_codec 0>;
            };
        };

or

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


As far as I know, only "mediatek,platform" was used at the beginning.
Next, hdmi-codec was introduced, and it followed the same style to get
phandle. Finally, it became three properties in mt8195, and the
implementation of mt8188 was inherited from mt8195.

I just glanced over the usage of dai links.
As I see it, I will replace the codec parts with dai link structure
like the example above first. It seems to be easier to extend more
codecs with the same tyle.

For platform part, I need more time to check if it is better to keep
the original implementation, because we still have to take SOF related 
implementation into consideration.

Yes, this one. I think this is preferred. But anyway the point is to use
sound-dai-cells, not pure (non-DAI) phandles).

OK, if you share common code it is fine.

Would be good.

OK
