/*

 * NOTES

 *

 *  The extended registers contain mixer settings which are largely

 *  untapped for the time being.

 *

 *  MPU401 and SPDIF are not supported yet.  I don't have the hardware

 *  to aid in coding and testing, so I won't bother.

 *

 *  To quickly load the module,

 *

 *  modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1

 *    sbdma16=5 wssport=0x530 wssirq=11 wssdma=0

 *

 *  This card has two mixers and two PCM devices.  I've cheesed it such

 *  that recording and playback can be done through the same device.

 *  The driver "magically" routes the capturing to the AD1848 codec,

 *  and playback to the SB16 codec.  This allows for full-duplex mode

 *  to some extent.

 *  The utilities in alsa-utils are aware of both devices, so passing

 *  the appropriate parameters to amixer and alsactl will give you

 *  full control over both mixers.
