 1.12  27-Oct-2012  chs split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.11  23-Nov-2011  jmcneill branches: 1.11.8;
Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From
the original ad-audiomp branch notes:

Add MP locking to the audio drivers.

Making the audio drivers MP safe is necessary before efforts
can be made to make the VM system MP safe.

The are two locks per device instance, an ISR lock and
a character device lock. The ISR lock replaces calls to
splaudio()/splx(), and will be held across calls to device
methods which were called at splaudio() before (e.g.
trigger_output). The character device lock is held across
calls to nearly all of the methods, excluding some only
used for initialization, e.g. get_locks.

Welcome to 5.99.57.

Missed in previous device_t/softc split commit for esa, pointed out by
xtraeme@
 1.9  09-Dec-2007  jmcneill branches: 1.9.10;
Merge jmcneill-pm branch.
 1.8  04-Mar-2007  christos branches: 1.8.14; 1.8.16; 1.8.24; 1.8.26;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.7  11-Dec-2005  christos branches: 1.7.26; 1.7.28;
merge ktrace-lwp.
 1.6  24-Mar-2005  jmcneill branches: 1.6.2;
Update my email address (the one listed hasn't been active in years).
 1.5  15-Jan-2005  kent branches: 1.5.2; 1.5.4;
ansify and KNF
 1.4  16-Mar-2002  jmcneill branches: 1.4.12;
Add multiple voice support to the ESS Allegro-1 / Maestro-3 family of
audio accelerators.

Mixing is done in hardware by the ASSP, but is limited to 4 simultaneous
channels due to the restricted "minisrc" image that we are currently
working with.

Due to limitations in the audio subsystem, I'm currently attaching multiple
'audio' devices to 'esa', one for each voice. Because of this hack, the
default ESA_NUM_VOICES is 1.
 1.3  13-Jan-2002  pooka branches: 1.3.2;
Add support for the driver to work after suspend/resume. Does nothing
fancy, works for the basic output case, but does not support programs
which use playback while going into suspend.

Sketched after code found in FreeBSD and Linux drivers.
 1.2  07-Jan-2002  jmcneill branches: 1.2.2; 1.2.4;
