There are not any major distributions that are still supporting kernels
older than 2.6.27 so we can remove many typedefs. The primary motivator
for this change is that kernel 5.0 is dropping support for timeval and
it would be ideal if the in-kernel time representation can
standardize on ktime_t, but 2.6.18 did not support the ktime
interface that was needed.

This fixes a long standing issue where, for CAS signaling, the RX bits were
sometimes misreported after span configuration before the first detected state
change.
The logic in the wct4xxp driver now matches that in the wcte43x driver and
wcte13xp drivers. The wcte12xp driver always polls the sigbits due to how
voicebus works and is not affected by this.

The octasic library is relatively large and is currently separately linked into
both the wcte13xp and wct4xxp libraries. This change moves it out into a

The bigest change from the drivers perspectives is that they must provide a

dahdi_genconf currently does not take into account the number of spans

installed in the system, it could be possible to have something like this in
/etc/dahdi/system.conf:
spans=1,1,...
spans=2,2,...
spans=3,3,...
spans=4,4,...
When what you really want is something like this:
spans=1,1,...
spans=2,2,...
spans=3,1,...
spans=4,2,...
Otherwise, spans 3 and 4 will be configured to not recover the clock from the
span which is most likely NOT what you want.

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.

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

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.

result in simultaneous accesses to these registers, this change will
hopefully save someone else some time in the future verifying that the
