| * Samsung Exynos5420 Clock Controller |
| |
| The Exynos5420 clock controller generates and supplies clock to various |
| controllers within the Exynos5420 SoC. |
| |
| Required Properties: |
| |
| - compatible: should be one of the following. |
| - "samsung,exynos5420-clock" - controller compatible with Exynos5420 SoC. |
| |
| - reg: physical base address of the controller and length of memory mapped |
| region. |
| |
| - #clock-cells: should be 1. |
| |
| Each clock is assigned an identifier and client nodes can use this identifier |
| to specify the clock which they consume. |
| |
| All available clocks are defined as preprocessor macros in |
| dt-bindings/clock/exynos5420.h header and can be used in device |
| tree sources. |
| |
| Example 1: An example of a clock controller node is listed below. |
| |
| clock: clock-controller@0x10010000 { |
| compatible = "samsung,exynos5420-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 CLK_UART2>, <&clock CLK_SCLK_UART2>; |
| clock-names = "uart", "clk_uart_baud0"; |
| }; |
