+* Samsung Exynos4 Clock Controller
+
+The Exynos4 clock controller generates and supplies clock to various controllers
+within the Exynos4 SoC. The clock binding described here is applicable to all
+SoC's in the Exynos4 family.
+
+Required Properties:
+
+- comptible: should be one of the following.
+ - "samsung,exynos4210-clock" - controller compatible with Exynos4210 SoC.
+ - "samsung,exynos4412-clock" - controller compatible with Exynos4412 SoC.
+
+- 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 controller. Each clock is
+assigned an identifier and client nodes use this identifier to specify the
+clock which they consume. Some of the clocks are available only on a particular
+Exynos4 SoC and this is specified where applicable.
