-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>;
-	};
