// This table assumes the UCB1400 codec.  It is also assumed that the driver of 
//   the UCB1400's touch screen controller capabilities is ignorant of this
//   module; that is one reason some of the registers are listed as not 
//   supported.  We don't want to overwrite another driver's values.
// A more complex system would require one of these for each supported codec,
//   plus an "active" version for each codec in the system.

// Default values are mostly per the UCB1400 documentation, if they are 
//  specified.  Variable rate is enabled and set for 44.1 KHz.
// All registers must have an initialization value for syntactic reasons,
//  even if they are read-only or not supported.  Many none-supported registers
//  are given the default values found in the AC'97 specification.
// Read-only registers have the expected readable value in the default value 
//  position of the entry.
