- *
- * Special thanks to Ensoniq
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/dsp1 additional DAC, like /dev/dsp, but outputs to mixer "SYNTH" setting
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
- * to be done in software. That is what /dev/dac is for. By now (Q2 1998)
- * there are several MIDI to PCM (WAV) packages, one of them is timidity.
- *
- * Revision history
- * 04.06.1998 0.1 Initial release
- * Mixer stuff should be overhauled; especially optional AC97 mixer bits
- * should be detected. This results in strange behaviour of some mixer
- * settings, like master volume and mic.
- * 08.06.1998 0.2 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.1998 0.3 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.1998 0.4 Fix realplayer problems - dac.count issues
- * 27.10.1998 0.5 Fix joystick support
- * -- Oliver Neukum (c188@org.chemie.uni-muenchen.de)
- * 10.12.1998 0.6 Fix drain_dac trying to wait on not yet initialized DMA
- * 23.12.1998 0.7 Fix a few f_file & FMODE_ bugs
- * Don't wake up app until there are fragsize bytes to read/write
- * 06.01.1999 0.8 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.1999 0.9 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.1999 0.10 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 07.04.1999 0.11 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * Another Alpha fix (wait_src_ready in init routine)
- * reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru>
- * Note: joystick address handling might still be wrong on archs
- * other than i386
- * 15.06.1999 0.12 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.13 Add pci_set_master
- * 03.08.1999 0.14 adapt to Linus' new __setup/__initcall
- * added kernel command line option "es1371=joystickaddr"
- * removed CONFIG_SOUND_ES1371_JOYPORT_BOOT kludge
- * 10.08.1999 0.15 (Re)added S/PDIF module option for cards revision >= 4.
- * Initial version by Dave Platt <dplatt@snulbug.mtview.ca.us>.
- * module_init/__setup fixes
- * 08.16.1999 0.16 Joe Cotellese <joec@ensoniq.com>
- * Added detection for ES1371 revision ID so that we can
- * detect the ES1373 and later parts.
- * added AC97 #defines for readability
- * added a /proc file system for dumping hardware state
- * updated SRC and CODEC w/r functions to accommodate bugs
- * in some versions of the ES137x chips.
- * 31.08.1999 0.17 add spin_lock_init
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.18 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 21.10.1999 0.19 Round sampling rates, requested by
- * Kasamatsu Kenichi <t29w0267@ip.media.kyoto-u.ac.jp>
- * 27.10.1999 0.20 Added SigmaTel 3D enhancement string
- * Codec ID printing changes
- * 28.10.1999 0.21 More waitqueue races fixed
- * Joe Cotellese <joec@ensoniq.com>
- * Changed PCI detection routine so we can more easily
- * detect ES137x chip and derivatives.
- * 05.01.2000 0.22 Should now work with rev7 boards; patch by
- * Eric Lemar, elemar@cs.washington.edu
- * 08.01.2000 0.23 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * 07.02.2000 0.24 Use pci_alloc_consistent and pci_register_driver
- * 07.02.2000 0.25 Use ac97_codec
- * 01.03.2000 0.26 SPDIF patch by Mikael Bouillot <mikael.bouillot@bigfoot.com>
- * Use pci_module_init
- * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.28 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 05.01.2001 0.29 Hopefully updates will not be required anymore when Creative bumps
- * the CT5880 revision.
- * suggested by Stephan Müller <smueller@chronox.de>
- * 31.01.2001 0.30 Register/Unregister gameport
- * Fix SETTRIGGER non OSS API conformity
- * 14.07.2001 0.31 Add list of laptops needing amplifier control
- * 03.01.2003 0.32 open_mode fixes from Georg Acher <acher@in.tum.de>
