/*
* ALSA SoC TLV320AIC3X codec driver
*
* Author: Vladimir Barinov, <vbarinov@embeddedalley.com>
* Copyright: (C) 2007 MontaVista Software, Inc., <source@mvista.com>
*
* Based on sound/soc/codecs/wm8753.c by Liam Girdwood
*
* This program is free software; you can redistribute it and/or modify
* it under the terms of the GNU General Public License version 2 as
* published by the Free Software Foundation.
*
* Notes:
* The AIC3X is a driver for a low power stereo audio
* codecs aic31, aic32, aic33, aic3007.
*
* It supports full aic33 codec functionality.
* The compatibility with aic32, aic31 and aic3007 is as follows:
* aic32/aic3007 | 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_disable_pin(codec, "MONO_LOUT"), etc.
