  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 firmware 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
