    +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.
