/*
* Driver for AMD7930 sound chips found on Sparcs.
* Copyright (C) 2002 David S. Miller <[EMAIL PROTECTED]>
*
* Based entirely upon drivers/sbus/audio/amd7930.c which is:
* Copyright (C) 1996,1997 Thomas K. Dyas ([EMAIL PROTECTED])
*
* --- Notes from Thomas's original driver ---
* This is the lowlevel driver for the AMD7930 audio chip found on all
* sun4c machines and some sun4m machines.
*
* The amd7930 is actually an ISDN chip which has a very simple
* integrated audio encoder/decoder. When Sun decided on what chip to
* use for audio, they had the brilliant idea of using the amd7930 and
* only connecting the audio encoder/decoder pins.
*
* Thanks to the AMD engineer who was able to get us the AMD79C30
* databook which has all the programming information and gain tables.
*
* Advanced Micro Devices' Am79C30A is an ISDN/audio chip used in the
* SparcStation 1+. The chip provides microphone and speaker interfaces
* which provide mono-channel audio at 8K samples per second via either
* 8-bit A-law or 8-bit mu-law encoding. Also, the chip features an
* ISDN BRI Line Interface Unit (LIU), I.430 S/T physical interface,
* which performs basic D channel LAPD processing and provides raw
* B channel data. The digital audio channel, the two ISDN B channels,
* and two 64 Kbps channels to the microprocessor are all interconnected
* via a multiplexer.
* --- End of notes from Thoamas's original driver ---
