   * NOTES:
   *
   * - we reuse the struct snd_akm4xxx record for storing the wm8770 codec data.
   *   both wm and akm codecs are pretty similar, so we can integrate
   *   both controls in the future, once if wm codecs are reused in
   *   many boards.
   *
   * - DAC digital volumes are not implemented in the mixer.
   *   if they show better response than DAC analog volumes, we can use them
   *   instead.

   *
   *   version 0.82: Stable / not all features work yet (no communication with AC97 secondary)
   *       added 64x/128x oversampling switch (should be 64x only for 96khz)
   *       fixed some recording labels (still need to check the rest)
   *       recording is working probably thanks to correct wm8770 initialization
   *
   *   version 0.5: Initial release:
   *           working: analog output, mixer, headphone amplifier switch
   *       not working: prety much everything else, at least i could verify that
   *                    we have no digital output, no capture, pretty bad clicks and poops
   *                    on mixer switch and other coll stuff.
