2b6d5d3826 wctdm24xxp: Remove 'pos' member from 'struct wctdm'.
The card position is only used during startup so we don't need to carry it
around in the strucuture.

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.

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
with any spinlocks held, and that the module is pinned in memory, and
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.

15182a4a18 wctdm24xxp, wcte12xp: Remove unused 'whichframe' parameter.
'cmd_dequeue_vpmadt032' in the wctdm24xxp and wcte12xp drivers no longer
care about which frame they are on.  The command will be packed into the
eframe specified by "writechunk".

5b08a20526 wctdm24xxp: Leave FXO (DAA) always in full-wave ring detect mode.
In zaptel commit 4096 [1], all the debouncing of ring signals were moved
into software as opposed to using the ring validation circuit in DAA.
That commit failed to remove the initial check and set of the ring
validation circuit.

5618e9e812 wcte12xp, wctdm24xxp: Convert vbb cache from kmem_cache to dma_pool.
The voicebus interface constantly uses the same buffers for moving data
to/from the card.  A fixed pool has less overhead in this case than
constantly mapping/unmapping the kmem_cache_alloced buffers.

Saves about ~2.608 us for each run of vb_isr on a 2.40 GHz Xeon test
machine.

b45e166253 wctdm24xxp: Add optional FXO digital loopback if DEBUG is defined.
This module parameter will allow patgen/pattest to be used only on FXO
ports. *ALL* FXO ports will be placed in digital loopback mode when
set.

The current intent is for this to be removed as an optional module
parameter when there is a channel by channel representation in sysfs.
Otherwise, a new IOCTL would have to be defined and a tool written in
order to support this. DAHDI-696.

bf3fe05dfb wct4xxp: Moving the transmit short detection behind debug module param.
This needs some more testing before it's on by default.  If the card is
otherwise functioning, these messages may be confusing to the user.  If
the card is not functioning, the driver can be reloaded with debug to
check for this condition.
