- cx88x-audio.c - Conexant CX23880/23881 audio downstream driver driver
-
- (c) 2001 Michael Eskin, Tom Zakrajsek [Windows version]

-
- -----------------------------------------------------------------------
-
- 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, one of the dscaler driver guy works
- for Conexant ...
