  62    Unlike software-only systems, device drivers interact with complex hardware.
  63    It's not useful to define symbolic names for every register bit in the
  64    device.  The name can only partially document the semantics and make
  65    the driver longer and more difficult to read.
  66    In general, only the important configuration values or bits changed
  67    multiple times should be defined symbolically.
