I replaced the SPI Engine connections in the adaq7980_bd.tcl with the
spi_engine_create procedure found in the spi_engine.tcl script. Through
these changes, a more generic instantiation for the spi_engine can be
achieved. I configured the parameters for axi_pwm_gen and axi_clkgen according
to the results in the SPI_Engine_Timing_Computations Excel where I created a file
for adaq7980.
I created the adaq7980_fmc.txt file for generating the system_constr.xdc file.
I modified the system_bd.tcl, system_top.v, system_constr.xdc and Readme.md files.
Also I regenerated the Makefile.
Update docs instructions in the README.md to recommend building the libraries before generating the documentation.
Fix misspellings in the SPI Engines.
Use hashlib to gen the reproducible ids, so these elements won't be committed at every build in the gh-pages branch.
Get username from environment variable, to use in the symbolator local installation path, dismissing user interaction for this.
Use modelParameter to extract the type from ip-xact parameters without the format field, and improve formatting.

This commit adds support for ADALM-PHASER, allowing the user to choose between the default PlutoSDR mode and Phaser mode
through a software controlled GPIO pin: phaser_enable.
The Generic TDD Engine was integrated to output a logic signal on the L10P pin, which connects to the input of the ADF4159,
when receiving an external synchronization signal on the L12N pin from the Raspberry Pi. Two additional TDD channels are used
to synchronize the TX/RX DMA transfer start:
- TDD CH1 is connected to the RX DMA, triggering the synchronization flag;
- TDD CH2 is connected to the TX unpacker's reset, backpressuring the TX DMA until deasserted.

Reference design for AD4858 20-bit, low noise 8-channel, SAR ADC with
buffered differential, wide common range picoamp inputs.
The design supports:
- CMOS and LVDS interfaces(at build time)
- Runtime sampling changes
- Store captured samples in RAM, through DMA (available via software support)
Documentation at: https://wiki.analog.com/resources/eval/user-guides/ad4858_fmcz/ad4858_fmcz_hdl
The axi_ad4858 IP core is design as the HDL interface for the AD4858 ADC.
Features:
- AXI based configuration
- LVDS and CMOS support
- Configurable number of active data lines (CMOS - build-time configurable)
- Oversampling support
- Supports packet formats 0,1,2 or 3
- CRC check support
- Real-time data header access
- Channel based raw data access(0x0408)
- Xilinx devices compatible

The project controls the AD3552R digital-to-analog converter and transmits data written in the DDR memory to the QSPI interface of the DAC.
The reference clock is generated by an axi_clkgen IP and is configured to output a 133MHz signal.
If both channels are enabled and data streaming is DDR the sample rate is 16.65MSPS.
If just one channel is enabled and data streaming is DDR the sample rate is 33.3MSPS.
The VADJ voltage should be set to 1.8V.

The custom interface IP for AD3552R DAC has more operation capabilities:
- 8b register read/write SDR/DDR
- 16b register read/write SDR/DDR
- data stream SDR/DDR ( clk_in/8 or clk_in/4 update rate)
- selectable input source : DMA/ADC/TEST_RAMP
- data out clock(SCLK) has clk_in/8 frequency when the converter is configured and clk_in/2 when the converter is in stream mode
- the IP reference clock (clk_in) can have a maximum frequency of 132MHz
- the IP has multiple device synchronization capability when the DMA is set as an input data source

-Updated description of some fields of these registers: REG_CHAN_CNTRL_1,
REG_CHAN_CNTRL_2, REG_CHAN_CNTRL_3, REG_CHAN_CNTRL_4, REG_USR_CNTRL_4,
and REG_USR_CNTRL_5
-Added two new registers, both with their own fields and description:
REG_CHAN_CNTRL_9 and REG_CHAN_CNTRL_10

The DDS for each channel was synchronized by the main channel.
One problem with this aporoach is that when a user sets a DDS that
is not from the main channel the sinchronization does not happend.
This behavior is not user friendly in IIO-Oscilloscope or within other
configuration methods.
This commit keeps all channels in sync by triggering the sync on all
channels from each individual channel.

Automate table generation for register maps.
Based on tfcollins' vger python scripts.
There are docs/adi_regmap_*.txt with more than one regmap per file,
so the logic changed to allow that.

It has a global option to set the default state (hidden or visible)

The parameters directive allows to almost automatically generate the
parameters table.
It allows to add rich descriptions to the parameters, such as references,
while checking if they exist in the *_hw.tcl file a obtaining the types
and default values.
However, it cannot obtain parameters generated from a foreach loop yet,
making it incompatible with the axi_dmac_hw.tcl file for example.
This commit also joins the other extensions into a single adi_links
extension.

Add support for DDS phase width greather than 16.
The software should read the DDS phase data width register and configure
the DDS init and increment registers accordingly, otherwise the obtained
DDS output frequency will not be the desired one for DDS phase width
different than 16.
DDS_incr = (f_out * 2^(phase_width) * clkratio)/f_if
