+description: |
+ Analog Devices Generic AXI ADC IP core for interfacing an ADC 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 ADC, while this IP core will interface
+ to the data-lines of the ADC and handle the streaming of data into
+ memory via DMA.
