953a317be3 wctdm24xxp: Drop 'flags' from 'struct wctdm_module'.
The voicebus cards only support the S110M FXS modules which are based on
the 3215. The module flags member was only used to hold whether we were
dealing with a 3210 or 3215 SLIC, so we can drop it since we always know
we'll have a 3215 based SLIC.

60406e1a0c wctdm24xxp: Remove modmap member from 'struct wctdm'.
We can already use the module type to determine presence of a module to
check. This also moves the background polling of the modules until after
the board is completely initialized because the module type may change
while the different types are being probed. This also means that we need
to preset the shadow registers for the FXS because otherwise the shadow
register will not have been read before the first time it's checked for
a power alarm.

77dfe92f26 wcte12xp, wctdm24xxp: Separate test for VPMADT032 and initialization.
Part of increasing system startup speed.

Splitting these two operations facilitate checking if there is a module
present synchronously on driver load from the actual load of the firmware and
configuration of the channels.

This will allow the presence of the VPM module to be flagged on the span
before registration, but load and configuration can happen in the background.
When the modules are eventually loaded via udev, there will be enough time
from the time the drivers are loaded to when dahdi_cfg will run to complete
the firmware load, eliminating the need to block the driver here.

82acfbd41d wcte12xp: Move the VPMADT032 test/configuration to module load time.
The firmware load of the VPMADT032 was moved to startspan because a
quad-span card in the same system would would lock interrupts for
several seconds to load VPMOCT064/128 firmware. Now that the wct4xxp
driver no longer locks interrupts while loading its VPM module this
driver can move the VPMADT032 check/load back to module load time.

This is also required so that the presence of a hardware echo canceler
is marked on the span before it is registered with dahdi-base.c.

dd33d6c357 dahdi: Update the dahdi_ec_chunk interface to support preec streams.
dahdi_ec_chunk is the function that saves the received audio and places
a signed linear copy of it in the pre echocanceled buffer on the
channel.  By splitting the input and output of this function into two
parameters, a driver that can provide separate pre and post ec streams
can pass them independently to DAHDI, without worrying about DAHDI
overwriting a stream that may have already been echocanceled by the
hardware.

Previously, the dahdi_ec_chunk interface took a received audio buffer
and overwrote it after canceling the echo.  Now the input and output
from the function are broken up in order to support hardware echocans
that have a different preechocan stream.

76df5ab26b dahdi: Allow dahdi_span_ops.[chan|span]config and startup to block.
This change ensures that the dahdi_span_ops callbacks are not called

also passes the struct file * pointer to the callbacks.

Passing the file pointer to the callbacks allows the board drivers to
check any flags on the file descriptor used to configure the
span/channel. The intent here is to allow dahdi_config to open the
/dev/dahdi/ctl file in a non-blocking mode in case there is a lengthy
processes that needs to happen as part of configuration.

155cb5a0b1 xpp: Remove obsolete XPP_DEBUGFS code
XPP_DEBUGFS code was some code used to send BRI D-Channel data
through debugfs for, well, debugging. Unused in recent years.
Time to remove.

bbb34d7f29 xpp: Remove obsolete and unused OLD_PROC code
OLD_PROC marked old and unused code that was used for writing to procfs.
It has long ago been replaced with different sysfs interfaces. Time
to remove it.

9146433e6d wcte12xp: Fix regression preventing VPMADT032 from loading.
Commit r9781, "wcte12xp, wctdm24xxp: Remove unused support for booting
VPMADT032 from SPI", introduced a bug that would prevent the VPMADT032
from ever being able to complete its startup. This regression did not
make it to any releases.

9c1880d31a dahdi: Enable DTMF A,B,C, and D digits.
This appears to be an old regression from zaptel r4063 [1] that would
prevent DAHDI from generating the A,B,C, and D digits due to
unintentional drop through on a case statement.

fcd4db20d1 dahdi: Bug fix for enabling buffer events
Introduced in rev 9905, this bug could cause buffer events to become
disabled if the kernel was unable to access userland data.

e591241187 dahdi: Add capability to generate events on buffer underruns and overruns
Add BUFFEVENTS and individual buffer event channel flags so that DAHDI can
notify userspace processes when it is dropping data.  This can be useful when
trouble shooting fax problems since DAHDI currently silently discards data
becasuse of scheduling latency.  With this change, Asterisk could log an event
as opposed to just leaving it up to the tone detectors to figure out there was
some unexpected phase shift.

d0093c16cc wcte12xp: If we cannot read the mode selection pins fail the module load.
Alexandre reported that on a particular server he would get a server
crash when loading the wcte12xp driver after receiving a line about a
timeout when trying to read the mode selection jumpers.

If the driver times out when trying to read the mode selection bits
there is a serious problem and it should not try to continue on with
configuration / registration.

868dd3f0d5 dahdi: Do not define dev_name if already backported.
RHEL 5.6 has backported dev_name in include/dahdi/devices.h.  We now need to
check for a back ported definition before defining our own version on pre
2.6.26 kernels.

3ae1b03082 dahdi: Group dahdi timers into "rates" for improved CPU utilization.
Most of the timers added to the kernel will be configured to fire at the
same rate. This allows one "wake_up" from interrupt context to wake up
all the waiters.  On one test system, I saw about a ~10% improvement in
CPU utilization when 10,000 timers were opened.
