   1* Samsung Exynos5440 Clock Controller
   2
   3The Exynos5440 clock controller generates and supplies clock to various
   4controllers within the Exynos5440 SoC.
   5
   6Required Properties:
   7
   8- comptible: should be "samsung,exynos5440-clock".
   9
  10- reg: physical base address of the controller and length of memory mapped
  11  region.
  12
  13- #clock-cells: should be 1.
  14
  15The following is the list of clocks generated by the controller. Each clock is
  16assigned an identifier and client nodes use this identifier to specify the
  17clock which they consume.

  55Example: An example of a clock controller node is listed below.
  56
  57        clock: clock-controller@0x10010000 {
  58                compatible = "samsung,exynos5440-clock";
  59                reg = <0x160000 0x10000>;
  60                #clock-cells = <1>;
  61        };
