Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

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