   4 * Author:      Vladimir Barinov, <vbarinov@embeddedalley.com>
   5 * Copyright:   (C) 2007 MontaVista Software, Inc., <source@mvista.com>
   6 *
   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.
