   2 * ALSA SoC TLV320AIC3X codec driver

  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.
