Merge tag 'asoc-v3.15-2' of... 

Merge tag 'asoc-v3.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

ASoC: Updates for v3.15

This is mostly a few additional fixes from Lars-Peter, a new driver and
cleaning up a git failure with merging the Intel branch (combined with
an xargs failure to pay attention to error codes).  The history lists a
bunch of additional commits for the branch but the content of those
commits is actually present already but not recorded in history due to
git failing.  Unfortunately xargs is used in the merge script and it
doesn't do a good job of noticing errors from the commands it invokes.

Device Tree bindings for the Armada 370 DB audio

================================================



These Device Tree bindings are used to describe the audio complex

found on the Armada 370 DB platform.



Mandatory properties:



 * compatible: must be "marvell,a370db-audio"



 * marvell,audio-controller: a phandle that points to the audio

   controller of the Armada 370 SoC.



 * marvell,audio-codec: a phandle that points to the analog audio

   codec connected to the Armada 370 SoC.



Example:



	sound {

	      compatible = "marvell,a370db-audio";

	      marvell,audio-controller = <&audio_controller>;

	      marvell,audio-codec = <&audio_codec>;

	      status = "okay";

	};

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,tlv320aic3120" - TLV320AIC3120 (mono speaker amp, MiniDSP)

    "ti,tlv320aic3111" - TLV320AIC3111 (stereo speaker amp, MiniDSP)



- reg - <int> -  I2C slave address





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.

- 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



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";

	reg = <0x18>;



	ai31xx-micbias-vg = <MICBIAS_OFF>;



	HPVDD-supply = <&regulator>;

	SPRVDD-supply = <&regulator>;

	SPLVDD-supply = <&regulator>;

	AVDD-supply = <&regulator>;

	IOVDD-supply = <&regulator>;

	DVDD-supply = <&regulator>;
