-Legacy audio driver for YMF7xx PCI cards.
-
-
-FIRST OF ALL
-============
-
-  This code references YAMAHA's sample codes and data sheets.
-  I respect and thank for all people they made open the informations
-  about YMF7xx cards.
-
-  And this codes heavily based on Jeff Garzik <jgarzik@pobox.com>'s
-  old VIA 82Cxxx driver (via82cxxx.c). I also respect him.
-
-
-DISCLIMER
-=========
-
- This driver is currently at early ALPHA stage. It may cause serious
- damage to your computer when used.
- PLEASE USE IT AT YOUR OWN RISK.
-
-
-ABOUT THIS DRIVER
-=================
-
-  This code enables you to use your YMF724[A-F], YMF740[A-C], YMF744, YMF754
- cards as "SoundBlaster Pro" compatible card. It can only play 22.05kHz /
- 8bit / Stereo samples, control external MIDI port.
- And it can handle AC'97 mixer of these cards.
-
-  If you want to use your card as recent "16-bit" card, you should use
- Alsa or OSS/Linux driver. Ofcource you can write native PCI driver for
- your cards :)
-
-
-INSTALL
-=======
-
-  First, it requires some sound driver modules in Linux kernel 
- (soundcore.o , sound.o, sb.o and uart401.o), so you should enable
- these modules at kernel configuration (please refer some other 
- documentations for configuration of kernel).
- And add the following line in /etc/modules.conf:
-
-  options sb support=1
-
- (NOTE: There are no need any configuration of sb modules)
-
- To compile ymfsb module, type 'make'.
- And copy it to /lib/modules/(kernel_version)/misc, type 'depmod -a'.
- 
-  This module also requires /usr/src/linux/drivers/sound/ac97.[ch].
- If your kernel doesn't have these files, you should upgrade your kernel.
-
-
-USAGE
-=====
-
- # modprobe ymfsb (options)
-
-
-OPTIONS FOR YMFSB
-=================
-
-  io           : SB base address     (0x220, 0x240, 0x260, 0x280)
-  synth_io     : OPL3 base address   (0x388, 0x398, 0x3a0, 0x3a8)
-  dma          : DMA number          (0,1,3)
-  spdif_out    : SPDIF-out flag      (0:disable 1:enable)
-
- These options will change in future...
-
-
-FREQUENCY
-=========
-
-  When playing sounds via this driver, you will hear its pitch is slightly
- lower than original sounds. Since this driver recognizes your card acts
- with 21.739kHz sample rates rather than 22.050kHz (I think it must be
- hardware restriction). So many players become tone deafness.
- To prevent this, you should express some options to your sound player
- that specify correct sample frequency. For example, to play your MP3 file
- correctly with mpg123, specify the frequency like following:
-
-  %  mpg123 -r 21739 foo.mp3
-
-
-SPDIF OUT
-=========
-
-  With installing modules with option 'spdif_out=1', you can enjoy your
- sounds from SPDIF-out of your card (if it had).
- Its Fs is fixed to 48kHz (It never means the sample frequency become 
- up to 48kHz. All sounds via SPDIF-out also 22kHz samples). So your
- digital-in capable components has to be able to handle 48kHz Fs.

-TODO
-====
- * support for multiple cards
-   (set the different SB_IO,MPU_IO,OPL_IO for each cards)
-
- * support for OPL (dmfm) : There will be no requirements... :-<
