+Texas Instruments - tlv320aic3x Codec module
+
+The tlv320aic3x serial control bus communicates through I2C protocols
+
+Required properties:
+
+- compatible - "string" - One of:
+ "ti,tlv320aic3x" - Generic TLV320AIC3x device
+ "ti,tlv320aic33" - TLV320AIC33
+ "ti,tlv320aic3007" - TLV320AIC3007
+ "ti,tlv320aic3106" - TLV320AIC3106
+ "ti,tlv320aic3104" - TLV320AIC3104
+
+
+- reg - <int> - I2C slave address
+
+
+Optional properties:
+
+- reset-gpios - GPIO specification for the active low RESET input.
+- ai3x-gpio-func - <array of 2 int> - AIC3X_GPIO1 & AIC3X_GPIO2 Functionality
+ - Not supported on tlv320aic3104
+- ai3x-micbias-vg - MicBias Voltage required.
+ 1 - MICBIAS output is powered to 2.0V,
+ 2 - MICBIAS output is powered to 2.5V,
+ 3 - MICBIAS output is connected to AVDD,
+ If this node is not mentioned or if the value is incorrect, then MicBias
+ is powered down.
+- ai3x-ocmv - Output Common-Mode Voltage selection:
+ 0 - 1.35V,
+ 1 - 1.5V,
+ 2 - 1.65V,
+ 3 - 1.8V
+- AVDD-supply, IOVDD-supply, DRVDD-supply, DVDD-supply : power supplies for the
+ device as covered in Documentation/devicetree/bindings/regulator/regulator.txt
+
+Deprecated properties:
+
+- gpio-reset - gpio pin number used for codec reset
+
+CODEC output pins:
+ * LLOUT
+ * RLOUT
+ * MONO_LOUT
+ * HPLOUT
+ * HPROUT
+ * HPLCOM
+ * HPRCOM
+
+CODEC input pins for TLV320AIC3104:
+ * MIC2L
+ * MIC2R
+ * LINE1L
+ * LINE1R
+
+CODEC input pins for other compatible codecs:
+ * MIC3L
+ * MIC3R
+ * LINE1L
+ * LINE2L
+ * LINE1R
+ * LINE2R
+
+The pins can be used in referring sound node's audio-routing property.
+
+Example:
+
+#include <dt-bindings/gpio/gpio.h>
+
+tlv320aic3x: tlv320aic3x@1b {
+ compatible = "ti,tlv320aic3x";
+ reg = <0x1b>;
+
+ reset-gpios = <&gpio1 17 GPIO_ACTIVE_LOW>;
+
+ AVDD-supply = <&regulator>;
+ IOVDD-supply = <&regulator>;
+ DRVDD-supply = <&regulator>;
+ DVDD-supply = <&regulator>;
+};
