The following is the list of clocks generated by the controller. Each clock is
assigned an identifier and client nodes 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.
