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