ASoC: Updates for v3.15

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:

 - Lots of cleanups from Takashi for enumerations; the original API for
   these was error prone so he's refactored lots of code to use more
   modern APIs which avoid issues.
 - Elimination of the ASoC level wrappers for I2C and SPI moving us
   closer to converting to regmap completely and avoiding some
   randconfig hassle.
 - Provide both manually and transparently locked DAPM APIs rather than
   a mix of the two fixing some concurrency issues.
 - Start converting CODEC drivers to use separate bus interface drivers
   rather than having them all in one file helping avoid dependency
   issues.
 - DPCM support for Intel Haswell and Bay Trail platforms.
 - Lots of work on improvements for simple-card, DaVinci and the Renesas
   rcar drivers.
 - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
   CSR SiRF SoC.

+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:
+
+codec: tlv320aic32x4@18 {
+	compatible = "ti,tlv320aic32x4";
+	reg = <0x18>;
+	clocks = <&clks 201>;
+	clock-names = "mclk";
+};
