+description: |
+ Analog Devices Generic AXI DAC IP core for interfacing a DAC device
+ with a high speed serial (JESD204B/C) or source synchronous parallel
+ interface (LVDS/CMOS).
+ Usually, some other interface type (i.e SPI) is used as a control
+ interface for the actual DAC, while this IP core will interface
+ to the data-lines of the DAC and handle the streaming of data from
+ memory via DMA into the DAC.
