+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@ff000000 {
+		compatible = "adi,axi-clkgen";
+		#clock-cells = <0>;
+		reg = <0xff000000 0x1000>;
+		clocks = <&osc 1>;
+	};
