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.
