2 * sound/pss.c
3 *
4 * The low level driver for the Personal Sound System (ECHO ESC614).

10 * Version 2 (June 1991). See the "COPYING" file distributed with this software
11 * for more info.
12 *
13 *
14 * Thomas Sailer ioctl code reworked (vmalloc/vfree removed)
15 * Alan Cox modularisation, clean up.
16 *
17 * 98-02-21: Vladimir Michl <vladimir.michl@upol.cz>
18 * Added mixer device for Beethoven ADSP-16 (master volume,
19 * bass, treble, synth), only for speakers.
20 * Fixed bug in pss_write (exchange parameters)
21 * Fixed config port of SB
22 * Requested two regions for PSS (PSS mixer, PSS config)
23 * Modified pss_download_boot
24 * To probe_pss_mss added test for initialize AD1848
25 * 98-05-28: Vladimir Michl <vladimir.michl@upol.cz>
26 * Fixed computation of mixer volumes
27 * 04-05-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
28 * Added code that allows the user to enable his cdrom and/or
29 * joystick through the module parameters pss_cdrom_port and
30 * pss_enable_joystick. pss_cdrom_port takes a port address as its
31 * argument. pss_enable_joystick takes either a 0 or a non-0 as its
32 * argument.
33 * 04-06-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
34 * Separated some code into new functions for easier reuse.
35 * Cleaned up and streamlined new code. Added code to allow a user
36 * to only use this driver for enabling non-sound components
37 * through the new module parameter pss_no_sound (flag). Added
38 * code that would allow a user to decide whether the driver should
39 * reset the configured hardware settings for the PSS board through
40 * the module parameter pss_keep_settings (flag). This flag will
41 * allow a user to free up resources in use by this card if needbe,
42 * furthermore it allows him to use this driver to just enable the
43 * emulations and then be unloaded as it is no longer needed. Both
44 * new settings are only available to this driver if compiled as a
45 * module. The default settings of all new parameters are set to
46 * load the driver as it did in previous versions.
47 * 04-07-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
48 * Added module parameter pss_firmware to allow the user to tell
49 * the driver where the fireware file is located. The default
50 * setting is the previous hardcoded setting "/etc/sound/pss_synth".
51 * 00-03-03: Christoph Hellwig <chhellwig@infradead.org>
52 * Adapted to module_init/module_exit
53 * 11-10-2000: Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
54 * Added __init to probe_pss(), attach_pss() and probe_pss_mpu()
55 * 02-Jan-2001: Chris Rankin
56 * Specify that this module owns the coprocessor
