/*
Legacy audio driver for YMF724, 740, 744, 754 series.
Copyright 2000 Daisuke Nagano <breeze.nagano@nifty.ne.jp>
Based on the VIA 82Cxxx driver by Jeff Garzik <jgarzik@pobox.com>
And ported to 2.3.x by Jeff Garzik too :) My it is a small world.
Distribued under the GNU PUBLIC LICENSE (GPL) Version 2.
See the "COPYING" file distributed with kernel source tree for more info.
-------------------------------------------------------------------------
It only supports SBPro compatible function of YMF7xx series s.t.
* 22.05kHz, 8-bit and stereo sample
* OPL3-compatible FM synthesizer
* MPU-401 compatible "external" MIDI interface
-------------------------------------------------------------------------
Revision history
Tue May 14 19:00:00 2000 0.0.1
* initial release
Tue May 16 19:29:29 2000 0.0.2
* add a little delays for reset devices.
* fixed addressing bug.
Sun May 21 15:14:37 2000 0.0.3
* Add 'master_vol' module parameter to change 'PCM out Vol' of AC'97.
* remove native UART401 support. External MIDI port should be supported
by sb_midi driver.
* add support for SPDIF OUT. Module parameter 'spdif_out' is now available.
Wed May 31 00:13:57 2000 0.0.4
* remove entries in Hwmcode.h. Now YMF744 / YMF754 sets instructions
in 724hwmcode.h.
* fixed wrong legacy_io setting on YMF744/YMF754 .
