+ * 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.
