-Texas Instruments - tlv320aic3x Codec module
-
-The tlv320aic3x serial control bus communicates through both I2C and SPI bus 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.
-
-I2C 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>;
-};
-
-SPI example:
-
-spi0: spi@f0000000 {
- tlv320aic3x: codec@0 {
- compatible = "ti,tlv320aic3x";
- reg = <0>; /* CS number */
- #sound-dai-cells = <0>;
- spi-max-frequency = <1000000>;
-
- AVDD-supply = <&regulator>;
- IOVDD-supply = <&regulator>;

- DVDD-supply = <&regulator>;
- ai3x-ocmv = <0>;
