2012-05-23convert span->spantype to enumerated typeTzafrir Cohen
* This is a minimal convertion -- everything compiles and looks OK. * We print a warning for spans registering without a spantype. * Low-level drivers may later want (but not required) to fold their internal representations to this canonical representation -- it will save code and make it more readable.

2011-10-26dahdi: Register devices instead of individual spans.Tzafrir Cohen
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 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. This generalizes similar concepts that were previously xpp specific. The conversion of the xpp code was almost entirely done by Oron and Tzafrir.

2011-06-02dahdi: Allow dahdi_span_ops.[chan|span]config and startup to block.Shaun Ruffell
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.

2011-06-02Remove unused variables.Shaun Ruffell
gcc-4.6 now warns about variables that are set but never used. Clean up unused variables everywhere except the oct612x subdirectory. The oct612x should go in a separate patch in case that needs to be pulled out into a separate project again.

2010-12-08dahdi: Removing loopstop maint functionRuss Meyerriecks
DAHDI_MAINT_LOOPSTOP is being removed due to the redundancy with DAHDI_MAINT_NONE. Also removing some timing logic, as amount of time a loopup or loopdown signal is held on the line, is now defined in userspace with dahdi_maint.

2010-10-20dahdi: Atomically set/test if channel has associated network device.Shaun Ruffell
Push all tests for the DAHDI_FLAGBIT_NETDEV flag behind a 'dahdi_have_netdev' function so if CONFIG_DAHDI_NET is not defined the compiler can just remove all the flag tests. Also, makes sure that the bit is checked / set atomically.

2010-09-24Move 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).

2010-07-26dahdi: Remove the 'pvt' member from dahdi_span.Shaun Ruffell
The vast majority of board drivers already keep the dahdi_span structure in a driver specific structure. The others were easily converted. This way board drivers can use the container_of macro to find what was previously pointed to by the "pvt" member of the span. One less thing to think about in the span structure. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8984 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-22Branch merge from the maintenance modes projectRuss Meyerriecks
* Added logic for both the single and dual/quad span cards for supporting local loopback (virtual loopback plug), network loopback, network payload loopback, loopup, and loopback transmitting. * Added logic for the dual/quad span driver to support exporting the performance and error counters including : - errored seconds - framing errors - coding violations - bipolar violations - crc4 errors - ebit errors - fas errors * Moved the error and performance counters into a substructure for all drivers taking advantage of dahdi_span bpvcount. * Modified the DAHDI_SPANSTAT ioctl interface, so I moved the old interface to DAHDI_SPANSTAT_V1. The new interface comes with a nice, new shiny packed struct dahdi_spaninfo. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8061 a0bf4364-ded3-4de4-8d8a-66a801d63aff
