rather: licenses) in the Astribank when a 2FXS6FXO module is used in

With commit (af3cd13501 "lib/string.c: remove strnicmp()") [1] dahdi can no
longer call strnicmp directly. strncasecmp was added into lib/string.c in kernel
version 2.6.22 so we'll map calls to strncasecmp to strnicmp for any kernel
before that.
This is necessary to compile against kernels >= 4.0.

Latest Astribank firmware (as of Rev. 11426 also supports some newer
hardware types, which will have the ID 203. Anyone installing this newer
version will now have 203 as an alias, but older versions will not have
it.
New firmware that includes a better way to identify hardware modules
type that does not require multiplexers.
This is firmware file FPGA_1161.201.hex rev. 11426.

This makes the open symmetrical with the close. It is also considered good
practice to not call through callbacks with spinlocks held.
I modified all the drivers where I could not tell whether it was necessary to
hold the chan->lock with interrupts disabled to simply take the lock inside the
callback.

* This will create a deadlock.

Some architectures, like arm, do not automatically pull in the definitions for
kzalloc and friends. This allows DAHDI to build on those platforms.

Fixes regression from bb63d03bba (before
v2.7.0). This failed to set the PCM mask on a CAS span when
DAHDI_AUDIO_NOTIFY was not set.
As the first channel of each xbus would be enabled (for
synchronization), a single call may still have passed.
This patch sets the PCM mask on any CAS channel explicitly.

XPP devices have implicit support for device registration and
unregistration. Even though it is only used for the legacy (non-hotplug)
configuration case, we still prefer to make it explicit.
This attribute would later allow a simpler implementation of the user
space (xpp-specific) tool dahdi_registration.

In an Astribank with >= 2 PRI ports, switching from E1 to T1 at run-time
may fail at the DAHDI_CHANCONFIG ioctl on the first channel in a span,
That is, on first run of dahdi_cfg, it fails on second span, on second:
it fails on third span, etc.
The code clears the D-channel information on the DAHDI_CHANCONFIG call
for the first channel in the span.
However The code tested for the global "channo" rather than the per-span
"chanpos" to check for the first channel in the span. This the test
failed.

* dahdi_registration writes multiple times to:
/sys/bus/astribanks/devices/*/*/span
* In some race cases this resulted in corruption and eventual kernel
panic.
* Until migration to "assigned-spans" is complete:
- Accept and ignore multiple "dahdi registrations" from user-space.

* We didn't handle proper E1/T1 transitions after device registration.
* Fix SPAN_REGISTERED(xpd):
It now checks for DAHDI_FLAGBIT_REGISTERED as well, as this flag is
set/clear by assign/unassign.
* From set_pri_proto():
- Always free/allocate channels
- Always call dahdi_init_span()
* Improve phonedev_cleanup() safety:
- NULL pointers after free.
- Zero number of channels at the end.
* Refactor channel allocation out of phonedev_init():
- Into phonedev_alloc_channels()
- Also called from xpd_init_span() to prevent duplicated logic.
- And called from set_pri_proto() to prevent our bug.

A new SysFS interface for FXS modules (XPDs):
* In /sys/bus/xpds/devices/<ll>:<m>:<n>/fxs_ring_registers
* Reading show current register values for NEON/TRAPEZ/NORMAL
* Modify the table via writing: "<column> <reg> <byte> [<byte>]"

echo "NEON 0x33 0x12" > \

xpp: refactor the FXS module ring settings into separate data structure:
* Update High VBAT initialization in init_card_1_30:
- Take the value used in set_vm_led_mode() (0x34)
- Now we don't need to set it over and over again in set_vm_led_mode()
* Create a unified ring_parameters[] array for all ring registers:
- Columns for 3 ring types (NEON, TRAPEZ, NORMAL)
- Used by new send_ring_parameters() function
* Now the set_vm_led_mode() simply calls send_ring_parameters()
* This cleanup would allow us to change ring parameters at runtime (by
updating the values in these tables).

* If userspace would run
modprobe xpp_usb && cat /sys/bus/astribanks/devices/xbus-00/waitfor_xpds
it would return immediately rather than wait for the Astribank to
initialize.
* We sometimes managed to read before getting the reply from the
astribank.
* Now we don't trust unit count at such an early stage.
* Instread we wait for the Astribank to reach a stable state (READY or FAIL)
before finish waiting for this astribank.

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.
