Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * 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
