Please use subject lines matching the style for the subsystem.  This is
helpful for identifying relevant patches and not getting your messages
deleted unread...

I'm sorry but this just doesn't explain what this patch is intended to
accomplish.  If we can talk to the AC'97 CODEC at all we can already
identify whatever constraints it has by looking at the ID registers so
it's not clear when or why a platform would need to use this.  It feels
like there is some underlying problem that you're trying to address.
