1	* Samsung Exynos5440 Clock Controller
2	
3	The Exynos5440 clock controller generates and supplies clock to various
4	controllers within the Exynos5440 SoC.
5	
6	Required Properties:
7	
8	- compatible: 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.
