Summary:                    IEC958 Capture and Universe support
Description: 
I had some spare time, so I thought I would continue adding features to the
aureon driver. The attached patch is the result:

Summary: IEC958 Capture mixer controls and Universe support

 * Added SPI read routine
 * Added IEC958 Capture mixer controls
 * Improved Universe support
 * Headphone Amp renamed to External Amplifier
 * Fixed GPIO bug in Prodigy code (There is no GPIO23 on ICE1724)

Well, I see your point about the CS bit for Prodigy. Actually I can't say
whether it will work for Prodigy, as I don't have that card. But since
there is no GPIO23 on ICE1724 (at least according to the datasheet), I
doubt that it worked before.
If I remember correct, the Aureon code also used the imaginary GPIO23
until someone found it out and corrected it. It is my belief that the
Aureon 7.1 Space and Prodigy 7.1 are completely identical, except that
Prodigy uses coax instead of optical, but naturally, I can't be sure.
Thing is, maybe nobody with the Prodigy attempted to used the S/PDIF out,
or maybe those who did, and found that it didn't work, didn't know where
to report the bug, or simply didn't care.

Fact is that there is only 23 GPIO pins (GPIO[22:0]) on ICE1724 although
there are room enough for one more in the CCS registers.

It would be nice to get feedback from a prodigy user however, but so far,
I haven't even found any other ALSA user, having an Aureon card.

A good point.
Ok, now I commited your patch to CVS.  Let's see whether anyone cries out
:)
