* 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.

* Copyright (c) 2003 Dimitromanolakis Apostolos <apostol@cs.utoronto.ca>
*
* 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.
