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

+ 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. The last
+ clock is the AXI bus clock that needs to be enabled so we can access the

-Binding for the axi-clkgen clock generator
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : shall be "adi,axi-clkgen-1.00.a" or "adi,axi-clkgen-2.00.a".
-- #clock-cells : from common clock binding; Should always be set to 0.
-- reg : Address and length of the axi-clkgen register set.
-- clocks : Phandle and clock specifier for the parent clock(s). This must
- either reference one clock if only the first clock input is connected or two
- if both clock inputs are connected. For the later case the clock connected
- to the first input must be specified first.
-
-Optional properties:
-- clock-output-names : From common clock binding.
-
-Example:
- clock@...00000 {
- compatible = "adi,axi-clkgen";
- #clock-cells = <0>;
- reg = <0xff000000 0x1000>;
- clocks = <&osc 1>;
