|
|
* Audio Command Interface (ACI) driver (sound/aci.c)
|
| 3 |
|
|
*
|
| 4 |
|
|
* ACI is a protocol used to communicate with the microcontroller on
|
| 5 |
|
|
* some sound cards produced by miro, e.g. the miroSOUND PCM12 and
|
| 6 |
|
|
* PCM20. The ACI has been developed for miro by Norberto Pellicci
|
| 7 |
|
|
* <pellicci@home.com>. Special thanks to both him and miro for
|
| 8 |
|
|
* providing the ACI specification.
|
| 9 |
|
|
*
|
| 10 |
|
|
* The main function of the ACI is to control the mixer and to get a
|
| 11 |
|
|
* product identification. On the PCM20, ACI also controls the radio
|
| 12 |
|
|
* tuner on this card, this is supported in the Video for Linux
|
| 13 |
|
|
* miropcm20 driver.
|
| 14 |
|
|
* -
|
| 15 |
|
|
* This is a fullfeatured implementation. Unsupported features
|
| 16 |
|
|
* are bugs... (:
|
| 17 |
|
|
*
|
| 18 |
|
|
* It is not longer necessary to load the mad16 module first. The
|
| 19 |
|
|
* user is currently responsible to set the mad16 mixer correctly.
|
| 20 |
|
|
*
|
| 21 |
|
|
* To toggle the solo mode for full duplex operation just use the OSS
|
| 22 |
|
|
* record switch for the pcm ('wave') controller. Robert

* Revision history:
|
| 26 |
|
|
*
|
| 27 |
|
|
* 1995-11-10 Markus Kuhn <mskuhn@cip.informatik.uni-erlangen.de>
|
| 28 |
|
|
* First version written.
|
| 29 |
|
|
* 1995-12-31 Markus Kuhn
|
| 30 |
|
|
* Second revision, general code cleanup.
|
| 31 |
|
|
* 1996-05-16 Hannu Savolainen
|
| 32 |
|
|
* Integrated with other parts of the driver.
|
| 33 |
|
|
* 1996-05-28 Markus Kuhn
|
| 34 |
|
|
* Initialize CS4231A mixer, make ACI first mixer,
|
| 35 |
|
|
* use new private mixer API for solo mode.
|
| 36 |
|
|
* 1998-08-18 Ruurd Reitsma <R.A.Reitsma@wbmt.tudelft.nl>
|
| 37 |
|
|
* Small modification to export ACI functions and
|
| 38 |
|
|
* complete modularisation.
|
| 39 |
|
|
* 2000-06-20 Robert Siemer <Robert.Siemer@gmx.de>
|
| 40 |
|
|
* Don't initialize the CS4231A mixer anymore, so the code is
|
| 41 |
|
|
* working again, and other small changes to fit in todays
|
| 42 |
|
|
* kernels.
|
| 43 |
|
|
* 2000-08-26 Robert Siemer
|
| 44 |
|
|
* Clean up and rewrite for 2.4.x. Maybe it's SMP safe now... (:
|
| 45 |
|
|
* ioctl bugfix, and integration of solo-mode into OSS-API,
|
| 46 |
|
|
* added (OSS-limited) equalizer support, return value bugfix,
|
| 47 |
|
|
* changed param aci_reset to reset, new params: ide, wss.
|
| 48 |
|
|
* 2001-04-20 Robert Siemer
|
| 49 |
|
|
* even more cleanups...
|
| 50 |
|
|
* 2001-10-08 Arnaldo Carvalho de Melo <acme@conectiva.com.br>
|
| 51 |
|
|
* Get rid of check_region, .bss optimizations, use set_current_state
