cx88x-audio.c - Conexant CX23880/23881 audio downstream driver driver

-----------------------------------------------------------------------
Lot of voodoo here. Even the data sheet doesn't help to
understand what is going on here, the documentation for the audio
part of the cx2388x chip is *very* bad.
Some of this comes from party done linux driver sources I got from
[undocumented].
Some comes from the dscaler sources, the dscaler driver guy works
for Conexant ...
