Hi Konrad,

Thank you for your review.

I will swap them:
	spdif_rx: spdif-rx { ... };
	spdif_tx: spdif-tx { ... };

I will change this series to:
	mi2s-playback-dai-link {
		link-name = "MI2S-LPAIF-RX-PRIMARY";

		codec {
			sound-dai = <&es8316>;
		};

		cpu {
			sound-dai = <&q6apmbedai PRIMARY_MI2S_RX>;
		};

		platform {
			sound-dai = <&q6apm>;
		};
	};

I will revise it to:
	lpass_qua_mi2s_data: qua-mi2s-data-state {
		pins = "gpio2", "gpio3", "gpio4";
		function = "qua_mi2s_data";
		drive-strength = <8>;
		bias-disable;
	};
