description: |
  The axi_clkgen IP core is a software programmable clock generator,
  that can be synthesized on various FPGA platforms.

properties:
  compatible:
    enum:
      - adi,axi-clkgen-2.00.a
      - adi,zynqmp-axi-clkgen-2.00.a

  clocks:
    description:
      Specifies the reference clock(s) from which the output frequency is
      derived. This must either reference one clock if only the first clock
      input is connected or two if both clock inputs are connected.
