+* Samsung Exynos5440 Clock Controller
+
+The Exynos5440 clock controller generates and supplies clock to various
+controllers within the Exynos5440 SoC.
+
+Required Properties:
+
+- comptible: should be "samsung,exynos5440-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 controller. Each clock is
+assigned an identifier and client nodes use this identifier to specify the
+clock which they consume.
