2 * ALSA SoC TLV320AIC3X codec driver
3 *
4 * Author: Vladimir Barinov, <vbarinov@embeddedalley.com>
5 * Copyright: (C) 2007 MontaVista Software, Inc., <source@mvista.com>

7 * Based on sound/soc/codecs/wm8753.c by Liam Girdwood

10 * it under the terms of the GNU General Public License version 2 as

12 *
13 * Notes:
14 * The AIC3X is a driver for a low power stereo audio
15 * codecs aic31, aic32, aic33, aic3007.
16 *
17 * It supports full aic33 codec functionality.
18 * The compatibility with aic32, aic31 and aic3007 is as follows:
19 * aic32/aic3007 | aic31
20 * ---------------------------------------
21 * MONO_LOUT -> N/A | MONO_LOUT -> N/A
22 * | IN1L -> LINE1L
23 * | IN1R -> LINE1R
24 * | IN2L -> LINE2L
25 * | IN2R -> LINE2R
26 * | MIC3L/R -> N/A
27 * truncated internal functionality in
28 * accordance with documentation
29 * ---------------------------------------
30 *
31 * Hence the machine layer should disable unsupported inputs/outputs by
32 * snd_soc_dapm_disable_pin(codec, "MONO_LOUT"), etc.
