   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
  15 The following is the list of clocks generated by the controller. Each clock is
  16 assigned an identifier and client nodes use this identifier to specify the
  17 clock which they consume.
