+Texas Instruments - tlv320aic26 Codec module
+
+The tlv320aic26 serial control bus communicates through I2C protocols
+
+Required properties:
+
+- compatible - "string" - One of:
+    "ti,tlv320aic26" - TLV320AIC26
+- reg - <int> -  SPI chip select
+
+CODEC input pins:
+  * MICIN
+  * AUX
+
+CODEC output pins:
+  * HPL
+  * HPR
+
+The pins can be used in referring sound node's audio-routing property.
+
+Example:
+
+tlv320aic26: tlv320aic26@0 {
+	compatible = "ti,tlv320aic26";
+	reg = <0>;
+};
+
+&spi0 {
+	pinctrl-names = "default", "sleep";
+	pinctrl-0 = <&spi0_pins>;
+	pinctrl-1 = <&spi0_sleep_pins>;
+
+	status = "okay";
+	ti,pindir-d0-out-d1-in = <1>;
+
+	tlv320aic26: tlv320aic26@1 {
+		compatible = "ti,tlv320aic26";
+		reg = <0x1>;
+		status = "okay";
+
+		spi-max-frequency = <2000000>;
+		spi-cpha;
+	};
+};
+
+sound {
+	compatible = "simple-audio-card";
+	simple-audio-card,name = "AM335x_SND";
+	simple-audio-card,format = "dsp_b";
+	/* SND_SOC_DAIFMT_CBM_CFM */
+	simple-audio-card,bitclock-master = <&tlv320aic26_codec>;
+	simple-audio-card,frame-master = <&tlv320aic26_codec>;
+	/* SND_SOC_DAIFMT_IB_NF */
+	simple-audio-card,bitclock-inversion;
+
+	simple-audio-card,cpu {
+		sound-dai = <&mcasp1>;
+		system-clock-frequency = <24576000>;
+	};
+
+	tlv320aic26_codec: simple-audio-card,codec {
+		sound-dai = <&tlv320aic26>;
+		system-clock-frequency = <24576000>;
+	};
