77437503a8 dahdi_dynamic: Since dynamic devices are 'parentless' we must name them.
This in conjunction with r10449 "A parent-less device should not crash dahdi",
this allows dahdi_dynamic spans to work post the dahdi_devices changes in
2.6.0.

The full address of the device is not used since kernels prior to 2.6.31 limit
the length of a devicename to 20 characters.  The full address of the device
can be pulled out of the "hardware_id" and "type" fields of the span.

This patch is just to get things working again. dahdi_dynamic devices *may*
still have issues if the auto_assign_spans module parameter is 0.

8297239209 dahdi_dynamic_eth: Move tx packet flushing to process context.
The masterspan can be, and often is, called with interrupts disabled but
dev_queue_xmit() needs to be called with interrupts enabled. This potentially
fixes a deadlock.

52b56c9848 A parent-less device should not crash dahdi
* A parent-less device should not crash dahdi:
  - Access span->parent->dev instead of span->parent-dev.parent
    in soem cases.
  - Access span->parent->dev via new inline span_device()
  - Use span_device() in all dahdi_dev_{dbg,info}()

* Allow low-level drivers to set their device name.
  - Drivers that don't use this feature get the default name
    based on the parent device name
  - Parent-less devices which don't set their name, fails
    to register with -EINVAL

eff796fd8f wcte12xp, wctdm24xxp: Add compile-time option to disable ASPM for PCIe devices.
Certain BIOSes appear to enable ASPM even though it is not fully supported by
the platform. Also, since the PCIe links for TDM cards are always in use it
does not make sense to allow them to transition to the disabled state.

Just turn off power management on the PCIe links completely. For more
information see http://lwn.net/Articles/449448/.

a2bfd1d4c2 wct4xxp: __t4_frame_in and __t4_framer_out slowdowns.
This is a partial revert of r10234 "wct4xxp: __t4_framer_in and
__t4_framer_out speedups."

There were some platform + firmware version combinations that would fail to
properly configure the framer with the aforementioned speedups. The originally
reported sympton was that interrupts would fail to start and while
troubleshooting I also saw cases where one of the spans would stay in alarm
after starting. By adding in additional reads to the version register, the
overall process of writing / reading from the framer control registers is
slowed down which increases reliability.

This change does *not* affect the main path of TDM data which is DMAed
directly into buffers in host memory and are not read / written to / from
framer registers directly.

3876f253a6 wctdm24xxp: Shorten RINGOFF debounce interval from 512ms to 128ms.
In commit r10168 "wctdm24xxp: Use time interval for debouncing FXO ring
detect" [1], I inadvertently changed the debounce interval of the RINGOFF
event from 128ms to 512ms. The result was a potential failure to detect CID,
depending on line conditions, since Asterisk would bump the rx gains on the
channel in the middle of the CID spill as opposed to before the CID spill.

This fixes a regression first introduced in DAHDI-Linux 2.6.0.

48b3cb8777 wct4xxp: VPM module creates noise on alternate channels on E1 spans.
The VPMOCT128 module was using the VPMOCT256 timeslots assigments which would
mean that channels that should be marked alaw were being set in ulaw. This
only affected E1 spans since by default all spans are configured for ulaw by
default.

This fixes a regression introduced in r10290 [1] "wct4xxp: Add support for
TE820 and VPMOCT256", first released in 2.6.0, that only affects E1 spans on a
quad and dual-span card when used with the hardware echocanceler.

b91ec305be wctdm24xxp: Fix bug if hook state on FXS changes before channel configuration.
If the hook state on an FXS port changes before the channel is
configured with dahdi_cfg it is possible to erroneously force the line
feed register open without setting a timer to clear it.

The result would be a "dead" channel that cannot be cleared unless the
driver is reloaded and warning in the kernel log that "0 is an invalid
signaling state for an FXS module".

This change makes the OFF_HOOK to ON_HOOK change behave just as the
ON_HOOK to OFF_HOOK change has.

9fd76d93c9 xpp: BRI: split multibyte functionality
* The zero lenth case (Magic request) was split into
  send_magic_request() function. It was not possible
  to move it into card_bri.c, because it is called
  directly from the general interface we provide for
  register read/write via sysfs/proc.

* The normal case (send_multibyte_request) was moved from
  card_global.c into card_bri.c

* This sets the stage to enable bundling of multibyte
  packets into frames (like we do for PCM).

6b6d047241 wct4xxp: Fail startup if not generating interrupts.
I've seen some platforms that do not properly route the interrupt from the
card to the host CPU. In these cases the card potentially could appear to be
greened up even though no data is flowing over the spans.

This change allows dahdi_cfg to return an error when this occurs, and also
ensures that all the spans are in RED alarm.

For example, dahdi_cfg output when the card is not generating interrupts:
  # dahdi_cfg
  DAHDI startup failed: Input/output error

And the kernel log will contain a string like:
  wct4xxp 0000:02:08.0: Interrupts not detected.

c4616c6c86 xpp: PRI: restore pri_protocol to R/W:
Restores the pri_protocol attribute of the XPD node in SysFS to be
writable. Fixes a minor regression from the pinned-spans fix, similar to
r10334.

* This attribute was made R/O in digium r10280 as part of the
  pinned-spans changes:
  - The E1/T1 settings were changed via new set_spantype() method
    which was called from dahdi when the 'spantype' dahdi attribute
    was written to.

  - This fails our init_card_4_* trying to write E1/T1 into our private
    attribute.

* Restored our old code (with minor modifications) so we
  can set E1/T1 the old way (writing to our 'pri_protocol' attribute)
  as well as the new way (when it will be used eventually).

1a79cb4fdc xpp: restore backward compat dahdi_registration
This restores a somewhat limited functionality of the "span"
write interface in the SysFS node of the span, broken by the
pinned-spans code.

* PROBLEM: dahdi-linux pinned-spans should work with existing dahdi-tools
  specifically the dahdi_registration tool.

* As a result, we should still be able to control dahdi registration
  order. However, registration is now in complete devices and not spans

* Restored dahdi_autoreg=[0/1] xpp module parameter:
  - It now refers to complete astribanks and not individual spans

* The xpp module sysfs "span" attribute:
  - Implemented write method (for dahdi_registration tool)
  - The first write of [1/0] to this attribute, registers/unregisters
    the complete astribank
  - Further writes are ignored (with DBG messages)

* Also, implemented new xbus_is_registered() function

* Once the new dahdi-tools are merged, we should turn deprecation
  messages from DBG() to NOTICE()

ce261cd03a wctdm24xxp, wcte12xp: Allow VPMADT032 commands more time to complete.
Since "wctdm24xxp: Probe for and configure modules in parallel." the
check for the VPMADT032 module was moved closer to after when the
interface was initialized. The 200ms timeout did not provide enough
time for the system to settle out after initial start. The result
was that sometimes after a cold boot the driver would fail to detect
any VPMADT032 modules.

This fixes a race condition that is not in any released branches.

f9c52bb271 dahdi: Allow 'spantype' to be changed before span assignement via sysfs.
For some boards, the linemode (E1/T1/J1) is software selectable but
needs to be configured before the spans were historically registered
since the line mode determines the channel count available on the span.

This change exports a "spantype" attribute from the dahdi_device that
can be used to set E1/T1/J1 before the spans are assigned. When
userspace writes to this attribute (in a <span offset>:<span type
string> format), and if the board driver has implemented a set_spantype
function in it's dahdi_span_ops, then the board driver can optionally
change it's mode before registration.

Also part of this change is breaking out the raw data structure
initialization of the spans / channels via the dahdi_init_device_spans
function since the board drivers may need to reallocate channels / spans
as part of this callback. For example, changing from T1 to E1 mode will
require allocating 7 new channels.

a6824019fb dahdi: Expose dahdi devices in sysfs.
This exposes dahdi devices in sysfs and also exposes attributes that
will allow user space to control the registration order in spans. This
facilitates loading drivers out of order yet keeping consistent
span/channel numbering, which in turn will eventually allow the
blacklist for DAHDI drivers to be removed. The default behavior,
controlled with the auto_register module parameter on dahdi is to number
the spans / channels in order like is currently done. So this change
does not introduce any new behavior by default.

 * Writing (anything) to this attribute returns the span to its
   unassigned state
 * Fix dahdi_chan_unreg() echocan refcount
 * Add safeguard against duplicate unassignment to _dahdi_unregister_span()
 * Remove the span from device_node list, only in dahdi_unregister_device()
   and not in dahdi_unregister_span()
 * Free allocated span->span_device in span_sysfs_remove()

935c9ba50a dahdi: Register devices instead of individual spans.
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.

33c31e9593 dahdi: start handling "surprise device removal".
This patch contains interim results while trying to make
device removal work correctly:

 * XPP has protections to prevent dahdi unregistration while
   channels are open -- they are now removed, so we can
   unregister immediately.

 * Handle processes in poll_wait():
   - Wake them during dahdi_chan_unreg() after the channel
     is gone (chan->channo = -1 or chan->file->private_data == NULL)

   - Test in every wait_event_interruptible() that the channel
     was not gone (chan->file->private_data)

   - Return correct values (POLLERR | POLLHUP) instead of
     some errno (would be important in the future if we
     modify asterisk to respond correctly to this condition.

 * Other issues:
   - If unregistered channel is being polled, than call msleep() before
     returning, to give other processes a chance (normally, asterisk
     has RT priority)

   - Call close_channel() from dahdi_chan_unreg() so it releases
     related tonezone

 * There is still a horrible race hidden by msleep(20) in
   dahdi_chan_unreg()

force close channels from dahdi_chan_unreg():

 * Mark them via DAHDI_FLAGBIT_OPEN
 * Call low-level driver close() method if available
 * What about other closing activities?
