| * Samsung Exynos5250 Clock Controller |
| |
| The Exynos5250 clock controller generates and supplies clock to various |
| controllers within the Exynos5250 SoC. |
| |
| Required Properties: |
| |
| - comptible: should be one of the following. |
| - "samsung,exynos5250-clock" - controller compatible with Exynos5250 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. |

| Example 1: An example of a clock controller node is listed below. |
| |
| clock: clock-controller@0x10010000 { |
| compatible = "samsung,exynos5250-clock"; |
| reg = <0x10010000 0x30000>; |
| #clock-cells = <1>; |
| }; |
| |
| Example 2: UART controller node that consumes the clock generated by the clock |
| controller. Refer to the standard clock bindings for information |
| about 'clocks' and 'clock-names' property. |
| |
| serial@13820000 { |
| compatible = "samsung,exynos4210-uart"; |
| reg = <0x13820000 0x100>; |
| interrupts = <0 54 0>; |
| clocks = <&clock 314>, <&clock 153>; |
| clock-names = "uart", "clk_uart_baud0"; |
| }; |
