-/*
- * Audio Command Interface (ACI) driver (sound/aci.c)
- *
- * ACI is a protocol used to communicate with the microcontroller on
- * some sound cards produced by miro, e.g. the miroSOUND PCM12 and
- * PCM20. The ACI has been developed for miro by Norberto Pellicci
- * <pellicci@home.com>. Special thanks to both him and miro for
- * providing the ACI specification.
- *
- * The main function of the ACI is to control the mixer and to get a
- * product identification. On the PCM20, ACI also controls the radio
- * tuner on this card, this is supported in the Video for Linux
- * miropcm20 driver.
- * -
- * This is a fullfeatured implementation. Unsupported features
- * are bugs... (:
- *
- * It is not longer necessary to load the mad16 module first. The
- * user is currently responsible to set the mad16 mixer correctly.
- *
- * To toggle the solo mode for full duplex operation just use the OSS
- * record switch for the pcm ('wave') controller. Robert
- * -
- *
- * Revision history:
- *
- * 1995-11-10 Markus Kuhn <mskuhn@cip.informatik.uni-erlangen.de>
- * First version written.
- * 1995-12-31 Markus Kuhn
- * Second revision, general code cleanup.
- * 1996-05-16 Hannu Savolainen
- * Integrated with other parts of the driver.
- * 1996-05-28 Markus Kuhn
- * Initialize CS4231A mixer, make ACI first mixer,
- * use new private mixer API for solo mode.
- * 1998-08-18 Ruurd Reitsma <R.A.Reitsma@wbmt.tudelft.nl>
- * Small modification to export ACI functions and
- * complete modularisation.
- * 2000-06-20 Robert Siemer <Robert.Siemer@gmx.de>
- * Don't initialize the CS4231A mixer anymore, so the code is
- * working again, and other small changes to fit in todays
- * kernels.
- * 2000-08-26 Robert Siemer
- * Clean up and rewrite for 2.4.x. Maybe it's SMP safe now... (:
- * ioctl bugfix, and integration of solo-mode into OSS-API,
- * added (OSS-limited) equalizer support, return value bugfix,
- * changed param aci_reset to reset, new params: ide, wss.
- * 2001-04-20 Robert Siemer
- * even more cleanups...
- * 2001-10-08 Arnaldo Carvalho de Melo <acme@conectiva.com.br>
- * Get rid of check_region, .bss optimizations, use set_current_state
