+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/exynos5440.h header and can be used in device
+tree sources.
 
 Example: An example of a clock controller node is listed below.
