The patch replaces magic numbers with macros defined in DT header
in exynos5440 clock bindings.

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.

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.
