Optional properties:
  - power-domains: a phandle to respective power domain node as described by
	generic PM domain bindings (see power/power_domain.txt for more
	information).

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/exynos5433.h header and can be used in device
tree sources.
