/*
* azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168).
* Copyright (C) 2002 by Andreas Mohr <hw7oshyuv3001@sneakemail.com>
*
* Framework borrowed from Bart Hartgers's als4000.c.
* Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
* found in a Fujitsu-Siemens PC ("Cordant", aluminum case).
* Other versions are:
* PCI168 A(W), sub ID 1800
* PCI168 A/AP, sub ID 8000
* Please give me feedback in case you try my driver with one of these!!

*
* NOTES
* Since Aztech does not provide any chipset documentation,
* even on repeated request to various addresses,
* and the answer that was finally given was negative
* (and I was stupid enough to manage to get hold of a PCI168 soundcard
* in the first place >:-P}),
* I was forced to base this driver on reverse engineering
* (3 weeks' worth of evenings filled with driver work).
* (and no, I did NOT go the easy way: to pick up a PCI128 for 9 Euros)
*
* The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
* for compatibility reasons) has the following features:
*
* - builtin AC97 conformant codec (SNR over 80dB)
* (really AC97 compliant?? I really doubt it when looking
* at the mixer register layout)
* - builtin genuine OPL3
* - full duplex 16bit playback/record at independent sampling rate
* - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
* - game port (legacy address support)
* - built-in General DirectX timer having a 20 bits counter
* with 1us resolution (FIXME: where is it?)
* - I2S serial port for external DAC
* - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
* - supports hardware volume control
* - single chip low cost solution (128 pin QFP)
* - supports programmable Sub-vendor and Sub-system ID
* required for Microsoft's logo compliance (FIXME: where?)
* - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
*
* Certain PCI versions of this card are susceptible to DMA traffic underruns
* in some systems (resulting in sound crackling/clicking/popping),
* probably because they don't have a DMA FIFO buffer or so.
* Overview (PCI ID/PCI subID/PCI rev.):
* - no DMA crackling on SiS735: 0x50DC/0x1801/16
* - unknown performance: 0x50DC/0x1801/10
*
* Crackling happens with VIA chipsets or, in my case, an SiS735, which is
* supposed to be very fast and supposed to get rid of crackling much
* better than a VIA, yet ironically I still get crackling, like many other
* people with the same chipset.
* Possible remedies:
* - plug card into a different PCI slot, preferrably one that isn't shared
* too much (this helps a lot, but not completely!)
* - get rid of PCI VGA card, use AGP instead
* - upgrade or downgrade BIOS
* - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX)
* Not too helpful.
* - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
*
* BUGS
* - when Ctrl-C'ing mpg321, the playback loops a bit
* (premature DMA playback reset?)
* - full-duplex sometimes breaks (IRQ management issues?).
* Once even a spontaneous REBOOT happened!!!
*
* TODO
* - test MPU401 MIDI playback etc.
* - power management (CONFIG_PM). See e.g. intel8x0 or cs4281.
* This would be nice since the chip runs a bit hot, and it's *required*
* anyway for proper ACPI power management. In other words: rest
* assured that I *will* implement this very soon; as soon as Linux 2.5.x
* has power management that's bugfree enough to work properly on my desktop.
* - figure out what all unknown port bits are responsible for
