9fb05e426e wcte43x, wcte13xp, wcaxx: Bump irqmisses counter when there are DMA underruns.
This makes the behavior of IRQ misses for these drivers behave the same as the
wcte12xp, wctdm24xxp, and wct4xxp drivers.

Previously irqmisses would never increase. The presence of underruns would still
show up in dmesg as latency bumps.

c03330ae9d Revert "wcte13xp: Export max_latency module parameter."
This was my mistake. This module parameter cannot be added on the 2.8 branch.

This reverts commit bb8512f56f.

ce03e88d77 wcte43x, wcte13xp: Use MSI interrupts if possible.
It was an oversight to prevent the wcte43x and wcte13xp drivers from using
Message Signaled interrupts during the switch to the wcxb library.

bb8512f56f wcte13xp: Export max_latency module parameter.
wcte13xp now has a max_latency module parameter like the wcaxx and wcte43x
drivers.

05bf6ac601 wcte13xp: Fix bug preventing recover timing from ever being set
A bug introduced in v2.8.0 prevented the recover timing configuration from
being set properly on the hardware. This caused the card to never go into
recovered timing mode.

3134b36d7e wcte13xp: Improve maintenance functions and error counters
From: Rus Meyerriecks <rmeyerriecks@digium.com>

* Removed work queue for maint interface as it is not needed in this driver
* Error counters are now accessible through the maint interface
* Consolidated and revised the big maint switch case
* Added loopup/loopdown code transmit logic to E1
* Now supports error/defect insersion

4707e19654 wcte13xp: Hold framer in reset to stop xmit on modprobe -r
From: Russ Meyerriecks <rmeyerriecks@digium.com>

The framer appears to continue transmitting a signal after modprobe -r. This
patch will leave the physical framer reset pin asserted to force the chip to
stop transmitting a signal when there is no driver attached.

e42548f2c5 wcte13xp: Migrate to wcxb library
From: Russ Meyerriecks <rmeyerriecks@digium.com>

Removed all the custom logic and replaced with the common platform wcxb stuff.

There are also changes in here to standardize the function prefix in this
driver to t13x_.

abe35059bc wcte13xp: Use interrupts for Falc alarms and signaling
From: Wendell Thompson <wthompson@digium.com>

Now uses framer interrupt vector polling (in the FPGA interrupt) for
alarm, loopcode, and signaling events eliminating continuous polling.
Now uses timer function for alarm and loopcode debouce, which only
executes during exception conditions.

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.

ce3f1f2650 wcte13xp: Workaround rare nmi on modprobe on select systems
With certain pci controllers that support pci hotplug, during the reset
sequence of the fpga, the host controller can get confused about the state of
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.
