-/*
- *  linux/sound/oss/dmasound/dmasound_awacs.c
- *
- *  PowerMac `AWACS' and `Burgundy' DMA Sound Driver
- *  with some limited support for DACA & Tumbler
- *
- *  See linux/sound/oss/dmasound/dmasound_core.c for copyright and
- *  history prior to 2001/01/26.
- *
- *	26/01/2001 ed 0.1 Iain Sandoe
- *		- added version info.
- *		- moved dbdma command buffer allocation to PMacXXXSqSetup()
- *		- fixed up beep dbdma cmd buffers
- *
- *	08/02/2001 [0.2]
- *		- make SNDCTL_DSP_GETFMTS return the correct info for the h/w
- *		- move soft format translations to a separate file
- *		- [0.3] make SNDCTL_DSP_GETCAPS return correct info.
- *		- [0.4] more informative machine name strings.
- *		- [0.5]
- *		- record changes.
- *		- made the default_hard/soft entries.
- *	04/04/2001 [0.6]
- *		- minor correction to bit assignments in awacs_defs.h
- *		- incorporate mixer changes from 2.2.x back-port.
- *		- take out passthru as a rec input (it isn't).
- *              - make Input Gain slider work the 'right way up'.
- *              - try to make the mixer sliders more logical - so now the
- *                input selectors are just two-state (>50% == ON) and the
- *                Input Gain slider handles the rest of the gain issues.
- *              - try to pick slider representations that most closely match
- *                the actual use - e.g. IGain for input gain... 
- *              - first stab at over/under-run detection.
- *		- minor cosmetic changes to IRQ identification.
- *		- fix bug where rates > max would be reported as supported.
- *              - first stab at over/under-run detection.
- *              - make use of i2c for mixer settings conditional on perch
- *                rather than cuda (some machines without perch have cuda).
- *              - fix bug where TX stops when dbdma status comes up "DEAD"
- *		  so far only reported on PowerComputing clones ... but.
- *		- put in AWACS/Screamer register write timeouts.
- *		- part way to partitioning the init() stuff
- *		- first pass at 'tumbler' stuff (not support - just an attempt
- *		  to allow the driver to load on new G4s).
- *      01/02/2002 [0.7] - BenH
- *	        - all sort of minor bits went in since the latest update, I
- *	          bumped the version number for that reason
- *
- *      07/26/2002 [0.8] - BenH
- *	        - More minor bits since last changelog (I should be more careful
- *	          with those)
- *	        - Support for snapper & better tumbler integration by Toby Sargeant
- *	        - Headphone detect for scremer by Julien Blache
- *	        - More tumbler fixed by Andreas Schwab
- *	11/29/2003 [0.8.1] - Renzo Davoli (King Enzo)
- *		- Support for Snapper line in
- *		- snapper input resampling (for rates < 44100)
- *		- software line gain control

-/* GENERAL FIXME/TODO: check that the assumptions about what is written to
-   mac-io is valid for DACA & Tumbler.
-
-   This driver is in bad need of a rewrite. The dbdma code has to be split,
-   some proper device-tree parsing code has to be written, etc...
