Mark, please, will you navigate me where DT binding is.
I just added this to my board dts and that's all:
	spi0: spi at f0000000 {
	...
		// audio codec
		tlv320aic3106: codec at 3 {
			compatible = "ti,tlv320aic3106";
			reg = <3>;
			#sound-dai-cells = <0>;
			spi-max-frequency = <1000000>;
			status = "okay";
			DRVDD-supply = <&reg_3v3>;
			AVDD-supply = <&reg_3v3>;
			IOVDD-supply = <&reg_3v3>;
			DVDD-supply = <&reg_1v8>;
			ai3x-ocmv = <0>;
		};
