1* Samsung Exynos4415 Clock Controller 2 3The Exynos4415 clock controller generates and supplies clock to various 4consumer devices within the Exynos4415 SoC. 5 6Required properties: 7 8- compatible: should be one of the following: 9 - "samsung,exynos4415-cmu" - for the main system clocks controller 10 (CMU_LEFTBUS, CMU_RIGHTBUS, CMU_TOP, CMU_CPU clock domains). 11 - "samsung,exynos4415-cmu-dmc" - for the Exynos4415 SoC DRAM Memory 12 Controller (DMC) domain clock controller. 13 14- reg: physical base address of the controller and length of memory mapped 15 region. 16 17- #clock-cells: should be 1. 18 19Each clock is assigned an identifier and client nodes can use this identifier 20to specify the clock which they consume. 21 22All available clocks are defined as preprocessor macros in 23dt-bindings/clock/exynos4415.h header and can be used in device 24tree sources. 25 26Example 1: An example of a clock controller node is listed below. 27 28 cmu: clock-controller@10030000 { 29 compatible = "samsung,exynos4415-cmu"; 30 reg = <0x10030000 0x18000>; 31 #clock-cells = <1>; 32 }; 33 34 cmu-dmc: clock-controller@105C0000 { 35 compatible = "samsung,exynos4415-cmu-dmc"; 36 reg = <0x105C0000 0x3000>; 37 #clock-cells = <1>; 38 }; 39
