+for an active slot as default, and the default active bits are at the LSB of
+the masks.

+Texas Instruments - tlv320aic31xx Codec module
+
+The tlv320aic31xx serial control bus communicates through I2C protocols
+
+Required properties:

+- compatible - "string" - One of:
+ "ti,tlv320aic310x" - Generic TLV320AIC31xx with mono speaker amp
+ "ti,tlv320aic311x" - Generic TLV320AIC31xx with stereo speaker amp
+ "ti,tlv320aic3100" - TLV320AIC3100 (mono speaker amp, no MiniDSP)
+ "ti,tlv320aic3110" - TLV320AIC3110 (stereo speaker amp, no MiniDSP)

+ "ti,tlv320aic3111" - TLV320AIC3111 (stereo speaker amp, MiniDSP)
+
+- reg - <int> - I2C slave address
+- HPVDD-supply, SPRVDD-supply, SPLVDD-supply, AVDD-supply, IOVDD-supply,
+ DVDD-supply : power supplies for the device as covered in
+ Documentation/devicetree/bindings/regulator/regulator.txt
+
+
+Optional properties:
+
+- gpio-reset - gpio pin number used for codec reset
+- ai31xx-micbias-vg - MicBias Voltage setting
+ 1 or MICBIAS_2_0V - MICBIAS output is powered to 2.0V
+ 2 or MICBIAS_2_5V - MICBIAS output is powered to 2.5V
+ 3 or MICBIAS_AVDD - MICBIAS output is connected to AVDD
+ If this node is not mentioned or if the value is unknown, then
+ micbias is set to 2.0V.
+
+CODEC output pins:
+ * HPL
+ * HPR
+ * SPL, devices with stereo speaker amp
+ * SPR, devices with stereo speaker amp
+ * SPK, devices with mono speaker amp
+ * MICBIAS
+
+CODEC input pins:
+ * MIC1LP
+ * MIC1RP
+ * MIC1LM
+
+The pins can be used in referring sound node's audio-routing property.
+
+Example:
+#include <dt-bindings/sound/tlv320aic31xx-micbias.h>
+
+tlv320aic31xx: tlv320aic31xx@18 {
+ compatible = "ti,tlv320aic311x";

+Texas Instruments - tlv320aic32x4 Codec module

+The tlv320aic32x4 serial control bus communicates through I2C protocols
+
+Required properties:
+ - compatible: Should be "ti,tlv320aic32x4"
+ - reg: I2C slave address
+ - supply-*: Required supply regulators are:
+ "iov" - digital IO power supply
+ "ldoin" - LDO power supply
+ "dv" - Digital core power supply
+ "av" - Analog core power supply
+ If you supply ldoin, dv and av are optional. Otherwise they are required
+ See regulator/regulator.txt for more information about the detailed binding
+ format.
+
+Optional properties:
+ - reset-gpios: Reset-GPIO phandle with args as described in gpio/gpio.txt
+ - clocks/clock-names: Clock named 'mclk' for the master clock of the codec.
+ See clock/clock-bindings.txt for information about the detailed format.
+
+
+Example:
+

+ compatible = "ti,tlv320aic32x4";
+ reg = <0x18>;
+ clocks = <&clks 201>;

+Widgets:
+
+This mainly specifies audio off-codec DAPM widgets.
+
+Each entry is a pair of strings in DT:
+
+ "template-wname", "user-supplied-wname"
+
+The "template-wname" being the template widget name and currently includes:
+"Microphone", "Line", "Headphone" and "Speaker".
+
+The "user-supplied-wname" being the user specified widget name.
+
+For instance:

+ "Line", "Line In Jack",
+ "Line", "Line Out Jack",
+ "Headphone", "Headphone Jack",
+ "Speaker", "Speaker External";
