Highlights:
* Implemented Phaser-servo. This requires recent gateware on Phaser.
* Implemented Phaser-MIQRO support. This requires the Phaser MIQRO gateware
variant.
* MSYS2 packaging for Windows.
* Hardware support:
- Implemented Phaser-servo. This requires recent gateware on Phaser.
- Implemented Phaser-MIQRO support. This requires the Phaser MIQRO gateware
variant.
- Sampler: fixed ADC MU to Volt conversion factor for Sampler v2.2+.
For earlier hardware versions, specify the hardware version in the device
database file (e.g. ``"hw_rev": "v2.1"``) to use the correct conversion factor.
- Metlino and Sayma support has been dropped due to complications with synchronous RTIO clocking.
* CPU (on softcore platforms) and AXI bus (on Zynq) are now clocked synchronously with the RTIO
clock, to facilitate implementation of local processing on DRTIO satellites, and to slightly
reduce RTIO latency.
* MSYS2 packaging for Windows, which replaces Conda. Conda packages are still available to
support legacy installations, but may be removed in a future release.
* Added channel names to RTIO errors.
* Full Python 3.10 support.

- Almazny mezzanine board for Mirny
- Phaser: improved documentation, exposed the DAC coarse mixer and ``sif_sync``, exposed upconverter calibration
and enabling/disabling of upconverter LO & RF outputs, added helpers to align Phaser updates to the
RTIO timeline (``get_next_frame_mu()``
RTIO timeline (``get_next_frame_mu()``).
- Urukul: ``get()``, ``get_mu()``, ``get_att()``, and ``get_att_mu()`` functions added for AD9910 and AD9912.
* Softcore targets now use the RISC-V architecture (VexRiscv) instead of OR1K (mor1kx).
* Gateware FPU is supported on KC705 and Kasli 2.0.

generated for some configurations.
* Phaser: fixed coarse mixer frequency configuration
* Mirny: Added extra delays in ``ADF5356.sync()``. This avoids the need of an extra delay before
calling `ADF5356.init()`.
calling ``ADF5356.init()``.
* The deprecated ``set_dataset(..., save=...)`` is no longer supported.
* The ``PCA9548`` I2C switch class was renamed to ``I2CSwitch``, to accomodate support for PCA9547,
* The ``PCA9548`` I2C switch class was renamed to ``I2CSwitch``, to accommodate support for PCA9547,
and possibly other switches in future. Readback has been removed, and now only one channel per
switch is supported.

"""Generates loop filter inputs from DDMTD outputs.
The input to the main DCXO lock loop filter is the difference between the
reference and main tags after unwrapping (see below).
The input to the helper DCXO lock loop filter is the difference between the
current reference tag and the previous reference tag after unwrapping.
When the WR PLL is locked, the following ideally (no noise/jitter) obtain:
- f_main = f_ref
- f_helper = f_ref * 2^N/(2^N+1)
- f_beat = f_ref - f_helper = f_ref / (2^N + 1) (cycle time is: dt=1/f_beat)
- the reference and main DCXO tags are equal to each other at every cycle
(the main DCXO lock drives this difference to 0)
- the reference and main DCXO tags both have the same value at each cycle
(the tag difference for each DDMTD is given by
f_helper*dt = f_helper/f_beat = 2^N, which causes the N-bit DDMTD counter
to wrap around and come back to its previous value)
Note that we currently lock the frequency of the helper DCXO to the
reference clock, not it's phase. As a result, while the tag differences are
controlled, their absolute values are arbitrary. We could consider moving
the helper lock to a phase lock at some point in the future...
Since the DDMTD counter is only N bits, it is possible for tag values to
wrap around. This will happen frequently if the locked tags happens to be
near the edges of the counter, so that jitter can easily cause a phase wrap.
But, it can also easily happen during lock acquisition or other transients.
To avoid glitches in the output, we unwrap the tag differences. Currently
we do this in hardware, but we should consider extending the processor to
allow us to do it inside the filters. Since the processor uses wider
signals, this would significantly extend the overall glitch-free
range of the PLL and may aid lock acquisition.
