The axi_dmac core generates requests which are both AXI3 and AXI4
compliant. This means it is possible to connect it to both a AXI3 or AXI4
slave port without needing a AXI protocol converter. Unfortunately it is
not possible to declare a port as both AXI3 and AXI4 compliant, so the core
has the C_DMA_AXI_PROTCOL_SRC and C_DMA_AXI_PROTOCOL_DEST parameters, which
allow to configure the protocol type of the corresponding AXI master
interface. Currently the default is always AXI4.
But when being used on ZYNQ it is most likely that the AXI master interface
of the DMAC core ends up being connected to the AXI3, so change the default
to AXI3 if the core is instantiated in a ZYNQ design.
The default can still be overwritten by explicitly setting the
configuration property.

Add support for querying the clock domains of the clock pins for the
axi_dmac controller. This allows the core to automatically figure out
whether its different parts run in different clock domains or not and setup
the configuration parameters accordingly.
Being able to auto-detect those configuration parameters makes the core
easier to use and also avoids accidental misconfiguration.
It is still possible to automatically overwrite the configuration
parameters by hand if necessary.

For the source controller use the pause signal that has been properly

When having multiple DMA cores sharing the same constraint file Vivado
seems to apply the constraints from the first core to all the other cores
when re-running synthesis and implementation from within the Vivado GUI.
This causes wrong timing constraints if the DMA cores have different
configurations. To avoid this issue use a TTCL template that generates a
custom constraint file for each DMA core instance.
This also allows us to drop the asynchronous clock detection hack from the
constraint file and move it to the template and only generate the CDC
constraints if the clock domains are asynchronous.

The synchronization interface is a single bidirectional line. Output for Master, input for Slave.
The sync_period value is relative to frame length and the digital interface clock. The actual synchronization
period will be: sync_period * frame_length * fb_clock_cycle
The memory mapped AXI interfaces for the AXI-DMAC are uni-directional.
Which means they are either write-only or read-only. Unfortunately the
Altera tools can't handle this, so we had to add dummy signals for the
other direction.
The Xilinx tools on the other hand handle uni-directional AXI interfaces
and in fact IPI can do a better job and use less resources when creating
the AXI interconnects when it knows that the interface is uni-directional.
So always disable the dummy ports for the IPI package.

For some reason, if a core has an AXI and an AXI Stream interface too, the tool sets the AXI interface's ASSOCIATED_RESET parameter to the AXI Stream interface's reset.
This cause an unconnected AXI reset port in the block design. This 'set_property' command intended to overwrite this automated setup.

This line controls the mux, which switch between hdl and software (GPIO) control of the ENABLE/TXNRX pins.
Fix the broken path and change the name from "tdd_enable" to "tdd_enabled".
Supported carrier are ZC706 and RFSOM.
The synchronization pulse is automatically generated by the master terminal, when TDD mode is enabled.
By default a terminal is slave, software must write 0x01 into TDD register 0x50.
Add tdd_gated_[tx/rx]_dmapath control bits to the TDD logic. With these control line, the user can choose between gated and free-running (like in FDD mode) data flow control.

Those were added by mistake. It does not seem to be legal Verilog, but for
