* Samsung Exynos4 Clock Controller The Exynos4 clock controller generates and supplies clock to various controllers within the Exynos4 SoC. The clock binding described here is applicable to all SoC's in the Exynos4 family. Required Properties: - comptible: should be one of the following. - "samsung,exynos4210-clock" - controller compatible with Exynos4210 SoC. - "samsung,exynos4412-clock" - controller compatible with Exynos4412 SoC. - 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. Some of the clocks are available only on a particular Exynos4 SoC and this is specified where applicable.
