4bfdd8bea5 dahdi: Remove "ddev" symlink before unregistering the span device.
This makes the order of operations for device removal symmetrical with those for
device addition. This change also eliminates the following warning when
unloading dahdi after dynamic spans have been created:

c0d52a04cb wctdm24xxp: Remove assigned callback.
For the spans exported by the wctdm24xxp, the channels are not going to change
after they are already registered.

This eliminates a problem when analog spans are unassigned/reassigned and the
not_ready goes negative, thereby causing many warnings in the kernel.

3a0905b1ec dahdi_dynamic: Create a span type for dynamic spans.
Fixes the following warning when loading the driver:

  dahdi: Warning: Span DYN/eth/eth1/00:50:c2:97:92:1d/1 didn't specify a spantype. Please fix driver!

The spantype is intended to be used by the auto configuration tools
(dahdi_genconf, pinned spans, etc..) but dynamic spans, since they are created
directly by dahdi_cfg, never take part in the pre-registration auto
configuration, therefore the span type was never used.

dd944f3362 sysfs: new driver attribute: master_span
* This changeset adds master_span as an attribute of the span's driver:
  /sys/bus/dahdi_spans/drivers/generic_lowlevel/master_span
* This is mainly used for debugging.
* Reading from it the master span number (or 0 if there is no master
  span).
* Writing a number to it, force specified span to be master
* Existing Alternatives:
  - grep "MASTER" from /proc/dahdi/*
  - cat /sys/bus/dahdi_spans/devices/span-*/is_sync_master

cbad5a7ae1 wcte43x: Do not grab reglock in handle_transmit/handle_receive.
If the driver is loaded with vpmsupport=0, then it was possible to create a
deadlock situation since the call into __dahdi_ec_chunk might then try to grab
the channel lock while already holding the reglock.

The purpose of grabbing reglock in the DMA routines was to protect the channel
array, which can be changed when linemode is changing. So instead, we'll
completely mask off that interrupt line from all CPUs when potentially changing
the channel array.

26efcf6902 wct4xxp, wcte13xp: Move the octasic DSP code into separate module.
The octasic library is relatively large and is currently separately linked into
both the wcte13xp and wct4xxp libraries. This change moves it out into a
separate loadable module.

The bigest change from the drivers perspectives is that they must provide a
table of callbacks instead of using statically linked Oct6100UserXxxxx functions
to allow the library to communicate with actual parts on the cards.

706dc43483 wct4xxp: Print warning in dmesg if span priority is not set correctly.
dahdi_genconf currently does not take into account the number of spans
configured for a particular board. Therefore if you have two dual span cards
installed in the system, it could be possible to have something like this in
/etc/dahdi/system.conf:

  spans=1,1,...
  spans=2,2,...
  spans=3,3,...
  spans=4,4,...

When what you really want is something like this:

  spans=1,1,...
  spans=2,2,...
  spans=3,1,...
  spans=4,2,...

Otherwise, spans 3 and 4 will be configured to not recover the clock from the
span which is most likely NOT what you want.

* Create a unified ring_parameters[] array for all ring registers:
  - Columns for 3 ring types (NEON, TRAPEZ, NORMAL)
  - Used by new send_ring_parameters() function
* Now the set_vm_led_mode() simply calls send_ring_parameters()

ce3f1f2650 wcte13xp: Workaround rare nmi on modprobe on select systems
With certain pci controllers that support pci hotplug, during the reset

the card and throw an nmi.

Known affected systems:
 HP proliant DL160 & DL360p
 Dell poweredge R520
 Super Micro X7SPA-HF

This patch attempts to work around that by removing the fpga reset sequence
from the driver startup, then setting various control registers to known
starting state values.

This patch removes the field upgradeable firmware logic temporarily for the
te133 card to prevent fpga reset.

The make_version script would test for a .version file in the proper location,

.version script correctly now, the Makefile can be slightly simpilfied and
always defer to it.

This has no user impact since build_tools/make_version was never used to read
