Currently, there are multiple missing break statements in two switch code
blocks. This makes the execution path to fall all the way down through
to the default cases, which makes the function ni_tio_set_gate_src() to
always return -EINVAL.
Fix this by adding the missing break statements.
Also, notice that due to the absence of the break statements,
the following pieces of code are unreachable:
1078 if (ret)
1079 return ret;
1080 /* 3. reenable & set mode to starts things back up */
1081 ni_tio_set_gate_mode(counter, src);
1098 if (ret)
1099 return ret;
1100 /* 3. reenable & set mode to starts things back up */
1101 ni_tio_set_gate2_mode(counter, src);
So, by adding the missing breaks, this patch also fixes the problem
above.

It's not obvious how the code prevents adding more than 31 elements to
the list and thus invoking undefined behaviour in the 1 << new_lbid
expression, and in practice causing ->lbid values to repeat every 32
elements.
But the definition of struct gb_loopback is local to loopback.c, and the
lbid field is entirely unused outside of this function, so it seems we
can just drop it entirely.

Adds ability to use device-global names in command args, in particular
cmd->start_arg (for NI_CtrArmStartTrigger), and cmd->scan_begin_arg or
cmd->convert_arg (either is used to specify NI_CtrGate, with preference
given to cmd->scan_begin_arg, if it is set).
The actual arguments of cmd->start_arg are not fully checked against known
register values for the particular devices because these are not documented
or currently known. This follows the precedence of prior versions of the
tio driver. Should these become known, they should be annotated in the
route_values tables and the set of lines in ni_tio_cmdtest should be
uncommented to allow the tests to be made.
This patch also adds interface functions that allow routes for particular
counter route destinations to be made/queried/unmade. This allows overseer
modules to implement test_route, connect_route, and disconnect_route. As a
part of these changes, various functions were cleaned up and clarified.
These new interface functions allow direct writing/reading of register
values. This is an example of exactly what the new device-global access
was intended to solve: the old interface was not consistent with other
portions of the ni_* drivers--it did not allow full register values to be
given for various MUXes. Instead, the old interface _did_ abstract away
some of the actual hardware from the underlying devices, but it was not
consistent with any other NI hardware. Allowing the device-global
identifiers to be used, the new patch provides for consistency across all
ni_* drivers. One final note: these changes provide for backwards
compatibility by allowing the older values to still be used in through the
pre-existing kernel interfaces--though not in the new device-global
test/dis/connect/route interfaces.

Implement device-global config interface for ni_mio devices. In
particular, this patch implements:
INSN_DEVICE_CONFIG_TEST_ROUTE,
INSN_DEVICE_CONFIG_CONNECT_ROUTE,
INSN_DEVICE_CONFIG_DISCONNECT_ROUTE,
INSN_DEVICE_CONFIG_GET_ROUTES
for the ni mio devices. This means that the new abstracted signal/terminal
names can be used to define signal routing with regards to the PFI
terminals and RTSI trigger bus lines.
This also adds ability to identify PFI and RTSI channels on the PFI and
RTSI subdevices using the new device-global names. This does not change
the values that are set for channel output selections using the subdevice
interfaces--these still require direct register values.
Annotates and updates tables of register values to reflect this new
implementation status.

See README for a thorough discussion of this content.
Adds tables of all register values for routing various signals to various
terminals on National Instruments hardware. This information is directly
compared to and taken from register-level programming documentation and/or
register-level programming examples as provided by National Instruments.
Furthermore, this information was mostly compared (favorably) to the
register values already used in the comedi drivers for NI hardware.
Adds tables of valid routes for many devices. This information is not
consistent from device to device, nor entirely consistent within device
families. One additional major challenge is that this information does not
seem to be obtainable in any programmatic fashion, neither through the
proprietary NIDAQmx(-base) c-libraries, nor with register level
programming, _nor_ through any documentation. In fact, the only consistent
source of this information is through the proprietary NI-MAX software,
which currently only runs on Windows platforms. A further challenge is
that this information cannot be exported from NI-MAX, except by screenshot.
The collection and maintenance of this information is somewhat tedious and
requires frequent re-examination and comparison of NI-MAX and/or the
NI-MHDDK documentation (register programming information) and NI-MHDDK
examples. Tools are added with this patch to facilitate generating CSV
files from the data tables. These CSV files can be used with a spreadsheet
program to provide better visual comparision with screenshots gathered from
NI-MAX. Tools are also added to regenerate the data tables from CSV
content--this greatly enhances updating data tables with large changes
(such as when adding devices).
