+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>;
