 *
 * Notes:
 *  The AIC3X is a driver for a low power stereo audio
 *  codecs aic31, aic32, aic33, aic3007.
 *
 *  It supports full aic33 codec functionality.
 *  The compatibility with aic32, aic31 and aic3007 is as follows:
 *    aic32/aic3007    |        aic31
 *  ---------------------------------------
 *   MONO_LOUT -> N/A  |  MONO_LOUT -> N/A
 *                     |  IN1L -> LINE1L
 *                     |  IN1R -> LINE1R
 *                     |  IN2L -> LINE2L
 *                     |  IN2R -> LINE2R
 *                     |  MIC3L/R -> N/A
 *   truncated internal functionality in
 *   accordance with documentation
 *  ---------------------------------------
 *
 *  Hence the machine layer should disable unsupported inputs/outputs by
 *  snd_soc_dapm_disable_pin(codec, "MONO_LOUT"), etc.
