199cd70d2c FPGA_1161.201.hex rev 10545: fix reset of XR1000
Previous commit (r10649) included an incorrect version. Including full message
from that commit for the description.

rev. 10502 of the FPGA firmware for the new E-Main rev. 4 fixes a potential
issue when used on Xorcom XR1000 systems: an issue with the power supply may
cause the unit to reset.

Note that there is no issue with previous models, with a normal setup of an
Astribank, or other XRx000 systems.

3d52bdd52f dahdi_dummy: Include timer.h instead of time.h
It appears that some kernel configurations do not include timer.h in any of
the include files that are included by dahdi_dummy. The timer_structs are
defined in timer.h and not time.h, so this change is correct even though I
never could find a configuation myself that actually failed to compile.

This has negligible impact since dahdi_dummy is not compiled by default.

034818dd81 dahdi_dynamic_eth: Make ztdeth_exit() symetrical with ztdeth_init() and fix race on unload.
Minor change to follow generally recommended practice. Prevents new packets
from being queued up for devices when they are about to be cleaned up. Also
clean up any skbs that may still be on the queue after unloading.

Also closes anoter potential kernel oops on module unload. It was possible to
delete the private structure while the master span process was running. The
result was an attempt to page memory from interrupt context.

Make sure that the pvt function is set and cleared under the zlock. Also do
not assume that the pvt pointer is valid in ztdeth_transmit.

d46ad9bca1 dahdi_dynamic: Remove calls to __module_get().
The board drivers are the ones calling the unregister function, and
therefore we do not need to worry about them unloading while calling the
destroy callback.

When destroying spans with the ioctl, replace __module_get() with
try_module_get. This avoids hitting a BUG in module_get on kernel versions <
2.6.29.

ALSO move the call to try_module_get out of the dahdi_dynamic_release function
and into destroy. This way if the destroy callback isn't called because the
dynamic driver is unloading the dynamic device can be left on the list to be
cleaned up by the dahdi_dynamic_unregister_driver function().

4ee22f19d1 dahdi_dynamic: Do not call into dahdi_dynamic without holding reference.
Instead of registering a function pointer, register a dahdi_dynamic_ops
structure that contains the owner as well as the ioctl callback. This way
dahdi.ko can bump up the reference count on dahdi_dynamic.ko before calling
the ioctl callback.

Also, use the registration mutex to guard against the module being unloaded
between the time the structure pointer was checked, and the module reference
is taken.

The driver makes the assumption that interrupts are disabled but this cannot

59caf11dbe xpp: FXS: added a 'lower_ringing_noise' parameter
* Adds a new parameter, 'lower_ringing_noise', to module xpd_fxs.

* Makes the "power-down" behaviour that was added
  in upstream svn r10478, switchable in runtime.

* By default (false), makes the vbat_h behave like it did
  before the power-down change.
  - I.e: vbat_h is held throughout the ringing period (during
    both ring-up/ring-down)
  - So this patch revert part of r10478

* When switched to true, activate the "power-down" behaviour.
  - I.e: vbat_h follows the ring-up/ring-down.
  - This behaviour lowers the noise caused by group ringing of
    FXS channels in the same unit, but causes problems with CallerID.

3e1c317323 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.

aa8bd2f546 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.

d1be14acf2 xpp: '%d' -> '%lu' when displaying module_refcount on kernel versions >= 3.3
Upstream commit bd77c047 "module: struct module_ref should contains long
fields" changed the return of module_refcount from int to unsigned long. This
change eliminates a warning from the string format specifier.

07c9bcecf2 dahdi: Remove __exit annotation from dahdi_sysfs_exit().
This removes the following warning:

Section mismatch in reference from the function init_module() to the function .exit.text:dahdi_sysfs_exit()
The function __init init_module() references a function __exit
dahdi_sysfs_exit(). This is often seen when error handling in the init
function uses functionality in the exit path.  The fix is often to remove the
__exit annotation of dahdi_sysfs_exit() so it may be used outside an exit
section.

2da38234d6 dahdi: Use monotonic clock for coretimer.
DAHDI internal timing currently uses the "wall clock" to determine how much
time is passing for mixing and timers. When the wall time changes, like when
the system time is set via ntp or date, DAHDI currently will display a
"Detected time shift" message since it believes there is too much audio to
mix. There may also be audio problems if the wall time is shifting
occasionally due to slewing of the clock.

Now use a monotonic clock to determine how much real-time has passed for
timing purposes. This makes DAHDI insensitive to any changes in the wall time
on the system.

This only applies when using DAHDI's internal timer like when there are not
any telphony cards installed. There are still potential audio problems if the
platform is unable to accurately determine the passage of time.

e07a70f403 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.

308a773fb2 sysfs channels: cleanup device files handling
* Shortcut CLASS_DEV_CREATE/CLASS_DEV_DESTROY. No need to pass repetitive
  data (and NULL) on every call.

* Create/remove fixed device files (ctl, timer, channel, pseudo) via
  generic code (fixed_devfiles_create()/fixed_devfiles_remove()) instead
  of repetitive code and flags.

* Try to make all removal/cleanup functions idempotent, so we can
  safely call them on any failure without the need for multiple goto
  destinations.

* Rename 'device_state_flags' to 'should_cleanup' and its member
  flags to a better/consistent naming.

* Rename dahdi_sysfs_exit() to dahdi_sysfs_cleanup() and call it from
  a new proper dahdi_sysfs_exit()

* In dahdi_sysfs_init(), handle dahdi_sysfs_chan_init() failures

* Add dahdi_dbg() message before creating/removing all DEVICES
  objects.

* Also move two KERN_INFO messages to a more correct locations:
  - The version reporting should be first (in dahdi-base.c)
  - The "Telephony... on major" reporting should be at the end
    of dahdi_sysfs_init()

1c6d3ad23c code cleanup: remove unused debug_printk()
The dahdi_echocan_* modules had an unused debug_printk() macro. Remove
them because:

* They were unused
* There were multiple definitions
* They were unsafe. Someone doing an
    if(foo)
      debug_printk(...);
    else
      do_something();
  may be surprised ;-)
* They used 'debug' as a debug level, while the rest of DAHDI debug
  macros treat it as a bit-field.

Leave only a single definition in wcte12xp/base.c which is safe.

5475f33f3d 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.

6485e9b0ba wctdm24xxp: FXS on-hook transmission timer incorrect.
The DAHDI_ONHOOKTRANSFER ioctl was incorrectly setting the ohttimer to 0. The
result was that an FXS port was leaving the on-hook transfer state before
finishing the transmission.

This was discovered while looking at why ./fxstest dtmfcid  was not able to
pass the DTMF callerid digits to an attached FXO port properly.

Fixes a regression introduced in r10167 "wctdm24xxp: Use interval for checking
FXS on hook transfer timer." [1], first released in 2.6.0.

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.

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.
