In ZCU102 LA01_CC_P|N are connected to regional clock, but in order to
receive a device clock properly we have to use pin which is connected
to a global clock buffer. Luckily SYSREF is connected to global clock
pin; swap to port to receive the device clock correctly.
Also, swap the ports in both ZC706 and A10SOC carriers.
mclk now generated by ps not axi clkgen ip. ADAU1761 expects a free
running clock and the i2s driver was switching the axi clkgen ip off
which was causing issues.
Cleanup placement constraints and let the tool have more freedom to
place and route the design. This is possible only after balancing the
memory and system clocks.
Minimize skew on synchronous CDC timing paths between clocks originating
from the same MMCM source. (sys_mem_clk and sys_cpu_clk)
This is required mostly by the smart interconnect.
The CLOCK_DELAY_GROUP property must be applied directly to the output net of BUFGs.
"prepare_incremental_compile" is defined as a phony target, but is also a
prerequisite of a real target. This will lead to a complete project build
every time make is called.
To fix the issue the functionality of prepare_incremental_compile target
was included in the generic project build target.
Software has to know which TIA channel was used for a particular capture.
Define an additional dummy ADC channel which will provide this
information. Currently this channel is always enabled.

Because the DMA transfers are going to be relatively small (< 2kbyte),
the DMA can handle the data rate, even when the frequency of the laser
driver pulse is set to its maximum value. (200 kHz)
The synchronization will be done by connecting the generated pulse to
the DMA's SYNC input. Although, to support 2 or 1 channel scenarios, we
need to use the util_axis_syncgen module to make sure that the DMA
catches the pulse, in cases when the pulse width is too narrow. (SYNC is
captures when valid and ready is asserted)
Also we have to reset the cpack IP before each pulse, to keep the DMA buffer's
relative starting point in time fixed, when only 2 or 1 channel is
active.
