Provides a more useful error message if the EEPROM cannot be found at
the specified address. Without this change a generic index out of range
error is raised.

Some close-in noise was observed on TX when using external references.
This change reduces the noise by changing U19 to select the GPSDO when
references are set to external. Also included is a change to properly
read and apply settings from the configuration file. This allows the
user to further quiet the transmission by adding 'enable_gps=False' to
the configuration file in order to power off the GPSDO.

When using enable_gps=0, the power to the LTE-Lite GPS chip is turned
off, and neither the reference sources (time/clock) nor the
location/time data (via gpsd) can be used.
This commit disables the gpsdo options for the set_time_source,
set_clock_source, and set_sync_source when enable_gps=0 is used, and
adds logging to inform the user about this.
This behaviour is consistent with X310, where `gpsdo` is only a valid
reference if the GPSDO module is plugged in.
The manual was also updated accordingly.
This value should be 9 to correspond with the rev J motherboards.
This property was renamed to mboard_last_rev_compat in a previous commit.
But mboard_max_rev is actually a more accurate description,
since it specifies the latest hardware revision that the software
is aware of. I renamed all references back to mboard_max_rev.
- Fixes a case where the e320 would be unable to lock to an external 10 MHz
reference
- Previously, calling set_time_source would set the reference clock source to
internal as a side effect
Newer revisions of the E320 and N3xx motherboards use EEPROM version 3,
and store a rev_compat field. The rev_compat is the last revision that
this hardware is compatible with. We now use that instead of simply the
revision.
- Turns the E310 into an MPM device (like N3xx, E320)
- Factor out common code between E320 and E310, maximize sharing between
the two devices
- Remove all pre-MPM E310 code that is no longer needed
- Modify MPM to remove all existing overlays before applying new ones
(this is necessary to enable idle image mode for E310)

The N320 has FPGA types (XQ, AQ) which cannot be derived from the mboard
regs in the same way as the non-QSFP variants. We therefore bite the
bullet and hardcode those.
Issue: Current code loads FPGA too early while many
essential peripherals such as net clocks are not brought up.
This change will make sure those are got init before FPGA loaded.

Add an argument to the UDP xport_mgr to adjust the xport sorting. This
enables Rhodium to use a different limit from Magnesium. Previously, the
sorting method would overload a link with both of Rhodium's higher-rate
streams.
Previously, the init() procedure of the n3xx class passed either
the user-provided or the default clock_source and time_source values
to initialize the clocking configuration.
When the user did not provide these parameters, the default values
were assigned, overriding whatever configuration the device was
previously initialized with. Therefore, a dboard reinit was forced
when the currently configured state of the N3xx device did not match
the default configuration (i.e. internal sources).
Now, the init() procedure still provides the clock_source and
time_source values; but, if the user does not provide the
parameters, the previously used values are assigned (i.e.
self._clock_source and/or self._time_source).
By the time MPM runs this n3xx init() procedure for the first time,
both self._clock_source and self._time_source have been initialized
with the default internal values anyways in the
_init_ref_clock_and_time() procedure.
This change prevents additional, unnecessary calls to the
set_sync_source() procedure, which ultimately causes a daughterboard
reinitialization when either a new clock or time source is requested.
- This is a combination of 5 commits.
- rh: add lo distribution board gpio expander
- rh: add lo distribution mpm functions
- rh: add code to conditionally initialize lo distribution
- rh: change empty i2c device from exception to assertion
- rh: add lo distribution board control
Add coercing behavior to set_time_source and set_clock_source to
a valid sync source. Also, skip set_sync_source if device already
set to the corresponding one.
Summary:
This change will allow correct args to pass from mboard to dboards,
that in turn can be useful for dboard manager.
Details:
In N310, the dboard manager needs the time source to be updated before
calling update_ref_clock_source(), because it will trigger a reinit of
the dboard, for which the time_source is essential to determine correct
clock synchronizer settings.
The special case is the white rabbit time source needs a different
internal ref_clock_frequency for the clock synchronizer than the passed
in ref_clock_freq.
Adding MPM Git hash and version to the MPM device info. This
information is currently only available through logs when MPM starts
(it is the first log message in usrp_hwd.py). Adding it to the device
info makes it accessible to any application which checks that, such as
uhd_usrp_probe.
Added set_sync_source method to set both the time and clock sources
without forcing a re-init twice. Modified the existing set_time_source
and set_clock_source methods to call into set_sync_source.
- Fix the syntax to open mboard-regs UIO objects, and change the open()
and close() functions to be private.
- We were calling open() twice in every context manager line- once
manually, and once in __enter__. This commit corrects those usages, and
allows the context manager to fully manage the opening and closing of
UIO objects.
Adding the following sensors:
- Catalina temperature, RSSI, and LO Lock sensors
- GPS lock, time, TPV, and SKY sensors
