+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.
