 * 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.
