+/*
+ * 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 fmport=0x388
+ *
+ * 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.
