| 4 | * The low level driver for the Personal Sound System (ECHO ESC614). |

| 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 |
Nick Andrew | 877d031 | 2009-01-26 11:06:57 +0100 | [diff] [blame] | 49 | * the driver where the firmware file is located. The default |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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 |
