2011-04-15dahdi: Move irq/irqmisses from dahdi_span into dahdi_device.Shaun Ruffell
These fields do not have anything to do with the span. Signed-off-by: Shaun Ruffell <sruffell@digium.com>
2011-04-15dahdi: register/unregister devices as opposed to individual spans.Shaun Ruffell
Increasingly, spans are implemented by devices that support more than a single span. Introduce a 'struct dahdi_device' object which explicitly contains multiple spans. This will also allow a cleaner representation of spans and devices in sysfs since order of arrival will not determine the layout of the devices. This also gives the core of dahdi a way to know the relationship between spans. Signed-off-by: Shaun Ruffell <sruffell@digium.com>

2011-02-10wct4xxp: Do not lock interrupts while loading the VPM firmware.Shaun Ruffell
Since the oct6100 API consumes less stack there is no longer a danger of overflowing our stack during load. Signed-off-by: Shaun Ruffell <sruffell@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9752 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2011-02-10wct4xxp: Reduce the memory footprint of the hardware echocanceler.Shaun Ruffell
This saves ~300K of kernel memory for each quad or dual span VPM. Due to the fact that this change disables caching of the NLP words (among other things), the time to disable the echocans appears to have increased by ~1ms.

2011-01-17wct4xxp: Perform an extended reset on PCI-Express cards by default.Shaun Ruffell
Extended reset is needed primarily with the PCI express version of the dual and quad-span cards. Enable it by default for those cards and allow it to be forced on or off globally for the driver as a compile time option. The options to force it should be able to come out if there aren't any further reports that the compile time option needs to be set.

2011-01-03wct4xxp: Hold the reglock longer when checking error counters.Shaun Ruffell
This is a very slight performance improvement. Eliminating the need to save the IRQ flags is probably more of a boost than grabbing and releasing the reglock.

Allow name of EC factory to vary based on channel Changed the echocan factory name to a function (get_name) called to get the name. This allows a factory to return a different name when being called in reference to a channel such as in the case of hardware echo cancellers. To further accommodate this change for HWEC, a new echocan_name function was added to the span ops struct and is used in hwec_factory in dahdi-base for all cards that support hardware echo cancellation.

2010-12-08dahdi: Fixed loopup/loopdown signalsRuss Meyerriecks
The loopup/loopdown T1 maintenance feature in the single through quad-span drivers now function properly, according to AT&T TR54016, by sending a full rate pattern down the line. T1.403 ESF/Data Link patterns are not supported currently. Also grouped all the maint reset register clears under a single irq lock to crank the performance up past 11.

The check for DEFINE_SPINLOCK was spread throughout the source tree. If not defined we can just define it in inlucde/dahdi/kernel.h.

2010-09-08wct4xxp: Update span-local struct with timing infoRuss Meyerriecks
dahdi_tool was incorrectly reporting all spans to be in local timing mode. This is because the driver tracks which span it's timing syncs to, within the card local struct "wc". We have to manually go through and copy timing updates to the span local structs because this is what dahdi_tool actually reads. dahdi-526 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9312 a0bf4364-ded3-4de4-8d8a-66a801d63aff

The transmit line open detection was pretty weak in that it trips upon receiving 32 consecutive zeroes. We were getting false positives from looping and other miscellaneous functions.

QuadFalc has the ability to test if the transformer is performing correctly.
