4 * Author: Vladimir Barinov, <vbarinov@embeddedalley.com>
5 * Copyright: (C) 2007 MontaVista Software, Inc., <source@mvista.com>
6 *
7 * Based on sound/soc/codecs/wm8753.c by Liam Girdwood
8 *
9 * Notes:
10 * The AIC3X is a driver for a low power stereo audio
11 * codecs aic31, aic32, aic33, aic3007.
12 *
13 * It supports full aic33 codec functionality.
14 * The compatibility with aic32, aic31 and aic3007 is as follows:
15 * aic32/aic3007 | aic31
16 * ---------------------------------------
17 * MONO_LOUT -> N/A | MONO_LOUT -> N/A
18 * | IN1L -> LINE1L
19 * | IN1R -> LINE1R
20 * | IN2L -> LINE2L
21 * | IN2R -> LINE2R
22 * | MIC3L/R -> N/A
23 * truncated internal functionality in
24 * accordance with documentation
25 * ---------------------------------------
26 *
27 * Hence the machine layer should disable unsupported inputs/outputs by
28 * snd_soc_dapm_disable_pin(codec, "MONO_LOUT"), etc.
