-/*
- * 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...
