* Version 2 (June 1991). See the "COPYING" file distributed with this software
* for more info.
*
*
* Thomas Sailer ioctl code reworked (vmalloc/vfree removed)
* Alan Cox modularisation, clean up.
*
* 98-02-21: Vladimir Michl <vladimir.michl@upol.cz>
* Added mixer device for Beethoven ADSP-16 (master volume,
* bass, treble, synth), only for speakers.
* Fixed bug in pss_write (exchange parameters)
* Fixed config port of SB
* Requested two regions for PSS (PSS mixer, PSS config)
* Modified pss_download_boot
* To probe_pss_mss added test for initialize AD1848
* 98-05-28: Vladimir Michl <vladimir.michl@upol.cz>
* Fixed computation of mixer volumes
* 04-05-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
* Added code that allows the user to enable his cdrom and/or
* joystick through the module parameters pss_cdrom_port and
* pss_enable_joystick. pss_cdrom_port takes a port address as its
* argument. pss_enable_joystick takes either a 0 or a non-0 as its
* argument.
* 04-06-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
* Separated some code into new functions for easier reuse.
* Cleaned up and streamlined new code. Added code to allow a user
* to only use this driver for enabling non-sound components
* through the new module parameter pss_no_sound (flag). Added
* code that would allow a user to decide whether the driver should
* reset the configured hardware settings for the PSS board through
* the module parameter pss_keep_settings (flag). This flag will
* allow a user to free up resources in use by this card if needbe,
* furthermore it allows him to use this driver to just enable the
* emulations and then be unloaded as it is no longer needed. Both
* new settings are only available to this driver if compiled as a
* module. The default settings of all new parameters are set to
* load the driver as it did in previous versions.
* 04-07-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
* Added module parameter pss_firmware to allow the user to tell
* the driver where the firmware file is located. The default
* setting is the previous hardcoded setting "/etc/sound/pss_synth".
* 00-03-03: Christoph Hellwig <chhellwig@infradead.org>
* Adapted to module_init/module_exit
* 11-10-2000: Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
* Added __init to probe_pss(), attach_pss() and probe_pss_mpu()
* 02-Jan-2001: Chris Rankin
* Specify that this module owns the coprocessor
