      1Texas Instruments - tlv320aic3x Codec module
      2
      3The tlv320aic3x serial control bus communicates through both I2C and SPI bus protocols
      4
      5Required properties:
      6
      7- compatible - "string" - One of:
      8    "ti,tlv320aic3x" - Generic TLV320AIC3x device
      9    "ti,tlv320aic33" - TLV320AIC33
     10    "ti,tlv320aic3007" - TLV320AIC3007
     11    "ti,tlv320aic3106" - TLV320AIC3106
     12    "ti,tlv320aic3104" - TLV320AIC3104
     13
     14
     15- reg - <int> -  I2C slave address
     16
     17
     18Optional properties:
     19
     20- reset-gpios - GPIO specification for the active low RESET input.
     21- ai3x-gpio-func - <array of 2 int> - AIC3X_GPIO1 & AIC3X_GPIO2 Functionality
     22				    - Not supported on tlv320aic3104
     23- ai3x-micbias-vg - MicBias Voltage required.
     24	1 - MICBIAS output is powered to 2.0V,
     25	2 - MICBIAS output is powered to 2.5V,
     26	3 - MICBIAS output is connected to AVDD,
     27	If this node is not mentioned or if the value is incorrect, then MicBias
     28	is powered down.
     29- ai3x-ocmv - Output Common-Mode Voltage selection:
     30	0 - 1.35V,
     31	1 - 1.5V,
     32	2 - 1.65V,
     33	3 - 1.8V
     34- AVDD-supply, IOVDD-supply, DRVDD-supply, DVDD-supply : power supplies for the
     35  device as covered in Documentation/devicetree/bindings/regulator/regulator.txt
     36
     37Deprecated properties:
     38
     39- gpio-reset - gpio pin number used for codec reset
     40
     41CODEC output pins:
     42  * LLOUT
     43  * RLOUT
     44  * MONO_LOUT
     45  * HPLOUT
     46  * HPROUT
     47  * HPLCOM
     48  * HPRCOM
     49
     50CODEC input pins for TLV320AIC3104:
     51  * MIC2L
     52  * MIC2R
     53  * LINE1L
     54  * LINE1R
     55
     56CODEC input pins for other compatible codecs:
     57  * MIC3L
     58  * MIC3R
     59  * LINE1L
     60  * LINE2L
     61  * LINE1R
