**
** FACILITY:
**
** DIGITAL Network Appliance Reference Design (DNARD)
**
** MODULE DESCRIPTION:
**
** This module contains the device driver for the ESS
** Technologies 1888/1887/888 sound chip. The code in sbdsp.c was
** used as a reference point when implementing this driver.
**
** AUTHORS:
**
** Blair Fidler Software Engineering Australia
** Gold Coast, Australia.
**
** CREATION DATE:
**
** March 10, 1997.
**
** MODIFICATION HISTORY:
**
** Heavily modified by Lennart Augustsson and Charles M. Hannum for
** bus_dma, changes to audio interface, and many bug fixes.
** ESS1788 support by Nathan J. Williams and Charles M. Hannum.
