- * sound/oss/pss.c
- *
- * The low level driver for the Personal Sound System (ECHO ESC614).
- *
- *
- * Copyright (C) by Hannu Savolainen 1993-1997
- *
- * OSS/Free for Linux is distributed under the GNU GENERAL PUBLIC LICENSE (GPL)
- * 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
