+ * Copyright (C) 2002, 2005 - 2011 by Andreas Mohr <andi AT lisas.de>
*
* Framework borrowed from Bart Hartgers's als4000.c.
* Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
* addresses illegally. So far unfortunately it looks like the very flexible
* ALSA AC97 support is still not enough to easily compensate for such a
* grave layout violation despite all tweaks and quirks mechanisms it offers.
+ * Well, not quite: now ac97 layer is much improved (bus-specific ops!),
+ * thus I was able to implement support - it's actually working quite well.
+ * An interesting item might be Aztech AMR 2800-W, since it's an AC97
+ * modem card which might reveal the Aztech-specific codec ID which
+ * we might want to pretend, too. Dito PCI168's brother, PCI368,
+ * where the advertising datasheet says it's AC97-based and has a
+ * Digital Enhanced Game Port.
* - builtin genuine OPL3 - verified to work fine, 20080506
* - full duplex 16bit playback/record at independent sampling rate
* - MPU401 (+ legacy address support, claimed by one official spec sheet)

"dump joy200 0x200 8", "dump mpu388 0x388 4", "dump joy 0xb400 8",
