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.
