2011-10-12wct4xxp: Fix condition where hardware echo canceler erroneously mutes DTMF.Shaun Ruffell
Commit r9750 "wct4xxp: Reduce the memory footprint of the hardware echocanceler.", as part of reducing the non-pageable memory required to support the VPMOCT064 and VPMOCT128, disabled caching of some hardware echocan registers. This resulted in more physical reads to the echo canceler. These new read transactions exposed an existing issue where sometimes reads could be turned into writes which put a channel into an unintended state preventing Asterisk from detecting any DTMF. This issue is resolved by ensuring that the write signal to the Octasic part is explicitly cleared between when the address is presented on the bus and when the read and chip select signals are asserted. The cost is an increase in the average time to enable / disable echo cancellation by about 5 us on one Intel Xeon X3220 test machine (~250ns increase per read from the Octasic part and 20 reads to enable / disable a channel). This commit resolves a behavioral regression first introduced in 2.5.0 and 2.4.1 which could take many calls before revealing itself. This change only affects cards with a VPMOCT128 or VPMOCT064 installed.

2011-10-12wct4xxp: Bug in timing cable with different span density cardsShaun Ruffell
The logic loops through the static cards[] array to determine timing, but the subloop was based off the current card's numspans member. This could cause a null dereference in the case where two cards of different span densities were connected via timing cables.

2011-05-27Move test for DEFINE_SPINLOCK into include/dahdi/kernel.hShaun Ruffell
The check for DEFINE_SPINLOCK was spread throughout the source tree. If not defined we can just define it in inlucde/dahdi/kernel.h. Now include/dahdi/kernel.h is the only place that references SPIN_LOCK_UNLOCKED (which breaks lockdep checking if DEFINE_SPINLOCK is otherwise defined in the kernel).

2011-01-21wct4xxp: 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.

2011-01-21wct4xxp: Update span-local struct with timing infoShaun Ruffell
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 Origin: http://svnview.digium.com/svn/dahdi?view=rev&rev=9312 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/branches/2.4@9654 a0bf4364-ded3-4de4-8d8a-66a801d63aff

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

The vast majority of board drivers already keep the dahdi_span structure in a driver specific structure. The others were easily converted.
