* Samsung Exynos5250 Clock Controller |
|
|
|
The Exynos5250 clock controller generates and supplies clock to various |
|
controllers within the Exynos5250 SoC. |
|
|
|
Required Properties: |
|
|
|
- compatible: 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. |
|
|
|
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/exynos5250.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@10010000 { |
|
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 CLK_UART2>, <&clock CLK_SCLK_UART2>; |
|
clock-names = "uart", "clk_uart_baud0"; |
|
};
