- * @set_target: Tell the platform which system sleep state is going to be

- *	@set_target() is executed right prior to suspending devices.  The
- *	information conveyed to the platform code by @set_target() should be
- *	disregarded by the platform as soon as @finish() is executed and if

- *	This callback is optional.  However, if it is implemented, the argument

- *	be ignored.
- *
- * @prepare: Prepare the platform for entering the system sleep state indicated
- *	by @set_target() or represented by the argument if @set_target() is not
- *	implemented.
- *	@prepare() is called right after devices have been suspended (ie. the
- *	appropriate .suspend() method has been executed for each device) and
- *	before the nonboot CPUs are disabled (it is executed with IRQs enabled).
- *	This callback is optional.  It returns 0 on success or a negative
- *	error code otherwise, in which case the system cannot enter the desired
- *	sleep state (@enter() and @finish() will not be called in that case).
- *
- * @enter: Enter the system sleep state indicated by @set_target() or
- *	represented by the argument if @set_target() is not implemented.
- *	This callback is mandatory.  It returns 0 on success or a negative
- *	error code otherwise, in which case the system cannot enter the desired
- *	sleep state.
- *
- * @finish: Called when the system has just left a sleep state, right after
- *	the nonboot CPUs have been enabled and before devices are resumed (it is
- *	executed with IRQs enabled).  If @set_target() is not implemented, the
- *	argument represents the sleep state being left.
- *	This callback is optional, but should be implemented by the platforms
- *	that implement @prepare().  If implemented, it is always called after

  *
  * The methods in this structure allow a platform to override the default
  * mechanism of shutting down the machine during a hibernation transition.
  *
  * All three methods must be assigned.
  *
- * @prepare: prepare system for hibernation
- * @enter: shut down system after state has been saved to disk
- * @finish: finish/clean up after state has been reloaded
- * @pre_restore: prepare system for the restoration from a hibernation image
- * @restore_cleanup: clean up after a failing image restoration
+ * @start: Tell the platform driver that we're starting hibernation.
+ *	Called right after shrinking memory and before freezing devices.
+ *
+ * @pre_snapshot: Prepare the platform for creating the hibernation image.
+ *	Called right after devices have been frozen and before the nonboot
+ *	CPUs are disabled (runs with IRQs on).
+ *
+ * @finish: Restore the previous state of the platform after the hibernation
+ *	image has been created *or* put the platform into the normal operation
+ *	mode after the hibernation (the same method is executed in both cases).
+ *	Called right after the nonboot CPUs have been enabled and before
+ *	thawing devices (runs with IRQs on).
+ *
+ * @prepare: Prepare the platform for entering the low power state.
+ *	Called right after the hibernation image has been saved and before
+ *	devices are prepared for entering the low power state.
+ *
+ * @enter: Put the system into the low power state after the hibernation image
+ *	has been saved to disk.
+ *	Called after the nonboot CPUs have been disabled and all of the low
+ *	level devices have been shut down (runs with IRQs off).
+ *
+ * @leave: Perform the first stage of the cleanup after the system sleep state
+ *	indicated by @set_target() has been left.
+ *	Called right after the control has been passed from the boot kernel to
+ *	the image kernel, before the nonboot CPUs are enabled and before devices
+ *	are resumed.  Executed with interrupts disabled.
+ *
+ * @pre_restore: Prepare system for the restoration from a hibernation image.

- *
- *  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

- *
- * Special thanks to Ensoniq
- *
- *  Supported devices:
- *  /dev/dsp    standard /dev/dsp device, (mostly) OSS compatible
- *  /dev/mixer  standard /dev/mixer device, (mostly) OSS compatible
- *  /dev/dsp1   additional DAC, like /dev/dsp, but outputs to mixer "SYNTH" setting
- *  /dev/midi   simple MIDI UART interface, no ioctl
- *
- *  NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
- *  to be done in software. That is what /dev/dac is for. By now (Q2 1998)
- *  there are several MIDI to PCM (WAV) packages, one of them is timidity.
- *
- *  Revision history
- *    04.06.1998   0.1   Initial release
- *                       Mixer stuff should be overhauled; especially optional AC97 mixer bits
- *                       should be detected. This results in strange behaviour of some mixer
- *                       settings, like master volume and mic.
- *    08.06.1998   0.2   First release using Alan Cox' soundcore instead of miscdevice
- *    03.08.1998   0.3   Do not include modversions.h
- *                       Now mixer behaviour can basically be selected between
- *                       "OSS documented" and "OSS actual" behaviour
- *    31.08.1998   0.4   Fix realplayer problems - dac.count issues
- *    27.10.1998   0.5   Fix joystick support
- *                       -- Oliver Neukum (c188@org.chemie.uni-muenchen.de)
- *    10.12.1998   0.6   Fix drain_dac trying to wait on not yet initialized DMA
- *    23.12.1998   0.7   Fix a few f_file & FMODE_ bugs
- *                       Don't wake up app until there are fragsize bytes to read/write
- *    06.01.1999   0.8   remove the silly SA_INTERRUPT flag.
- *                       hopefully killed the egcs section type conflict
- *    12.03.1999   0.9   cinfo.blocks should be reset after GETxPTR ioctl.
- *                       reported by Johan Maes <joma@telindus.be>
- *    22.03.1999   0.10  return EAGAIN instead of EBUSY when O_NONBLOCK
- *                       read/write cannot be executed
- *    07.04.1999   0.11  implemented the following ioctl's: SOUND_PCM_READ_RATE, 
- *                       SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS; 
- *                       Alpha fixes reported by Peter Jones <pjones@redhat.com>
- *                       Another Alpha fix (wait_src_ready in init routine)
- *                       reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru>
- *                       Note: joystick address handling might still be wrong on archs
- *                       other than i386
- *    15.06.1999   0.12  Fix bad allocation bug.
- *                       Thanks to Deti Fliegl <fliegl@in.tum.de>
- *    28.06.1999   0.13  Add pci_set_master
- *    03.08.1999   0.14  adapt to Linus' new __setup/__initcall

- *                       Added detection for ES1371 revision ID so that we can
- *                       detect the ES1373 and later parts.
- *                       added AC97 #defines for readability
