1 | * Samsung Exynos4 Clock Controller | ||
2 | |||
3 | The Exynos4 clock controller generates and supplies clock to various controllers | ||
4 | within the Exynos4 SoC. The clock binding described here is applicable to all | ||
5 | SoC's in the Exynos4 family. | ||
6 | |||
7 | Required Properties: | ||
8 | |||
9 | - comptible: should be one of the following. | ||
10 | - "samsung,exynos4210-clock" - controller compatible with Exynos4210 SoC. | ||
11 | - "samsung,exynos4412-clock" - controller compatible with Exynos4412 SoC. | ||
12 | |||
13 | - reg: physical base address of the controller and length of memory mapped | ||
14 | region. | ||
15 | |||
16 | - #clock-cells: should be 1. | ||
17 | |||
18 | The following is the list of clocks generated by the controller. Each clock is | ||
19 | assigned an identifier and client nodes use this identifier to specify the | ||
20 | clock which they consume. Some of the clocks are available only on a particular | ||
21 | Exynos4 SoC and this is specified where applicable. | ||

1 | * Samsung Exynos5440 Clock Controller | ||
2 | |||
3 | The Exynos5440 clock controller generates and supplies clock to various | ||
4 | controllers within the Exynos5440 SoC. | ||

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. | ||
