+Binding for simple fixed-rate clock sources.
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be "fixed-clock".
+- #clock-cells : from common clock binding; shall be set to 0.
+- clock-frequency : frequency of clock in Hz. Should be a single cell.
+
+Optional properties:
+- clock-accuracy : accuracy of clock in ppb (parts per billion).
+		   Should be a single cell.
+- clock-output-names : From common clock binding.
+
+Example:
+	clock {
+		compatible = "fixed-clock";
+		#clock-cells = <0>;
+		clock-frequency = <1000000000>;
+		clock-accuracy = <100>;
+	};
