+* Samsung Exynos5260 Clock Controller
+
+The Exynos5260 clock controller encalsulate all CMUs which are
+instantiaited independently from the device-tree. As a whole,
+these CMUs generates and supplies clocks to various controllers
+within the Exynos5260 SoC.
+
+Required Properties:
+
+- compatible: should be one of the following.
+ - First compatible should be one of the following
+ "exynos5260-cmu-top"
+ "exynos5260-cmu-peri"
+ "exynos5260-cmu-egl"
+ "exynos5260-cmu-kfc"
+ "exynos5260-cmu-g2d"
+ "exynos5260-cmu-mif"
+ "exynos5260-cmu-mfc"
+ "exynos5260-cmu-g3d"
+ "exynos5260-cmu-fsys"
+ "exynos5260-cmu-aud"
+ "exynos5260-cmu-isp"
+ "exynos5260-cmu-gscl"
+ "exynos5260-cmu-disp"
+ - Second compatible should be "samsung,exynos5260-clock".
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- #clock-cells: should be 1.
+
+The following is the list of clocks generated by the each controller. Each
+clock is assigned a MACRO constant. These constants are defined in
+"dt-bindings/clk/exynos5260-clk.h". DT client nodes use this MACRO to specify
+the clock which they consume.
