Vladimir Barinov 44d0a87995 [ALSA] ASoC TLV320AIC3X codec driver 
This patch adds ALSA SoC support for TI TLV320AIC3X audio codecs.
The features that are supported:
     o Capture/Playback/Bypass.
     o 16/20/24/32 bit audio.
     o 8k - 96k sample rates.
     o codec master only mode
     o DAPM.

*
* Notes:
* The AIC3X is a driver for a low power stereo audio
* codecs aic31, aic32, aic33.
*
* It supports full aic33 codec functionality.
* The compatibility with aic32, aic31 is as follows:
* aic32 | aic31
* ---------------------------------------
* MONO_LOUT -> N/A | MONO_LOUT -> N/A
* | IN1L -> LINE1L
* | IN1R -> LINE1R
* | IN2L -> LINE2L
* | IN2R -> LINE2R
* | MIC3L/R -> N/A
* truncated internal functionality in
* accordance with documentation
* ---------------------------------------
*
* Hence the machine layer should disable unsupported inputs/outputs by
* snd_soc_dapm_set_endpoint(codec, "MONO_LOUT", 0), etc.
