  1. * Samsung Exynos5410 Clock Controller
  2. The Exynos5410 clock controller generates and supplies clock to various
  3. controllers within the Exynos5410 SoC.
  4. Required Properties:
  5. - compatible: should be "samsung,exynos5410-clock"
  6. - reg: physical base address of the controller and length of memory mapped
  7. region.
  8. - #clock-cells: should be 1.
  9. All available clocks are defined as preprocessor macros in
  10. dt-bindings/clock/exynos5410.h header and can be used in device
  11. tree sources.
  12. External clock:
  13. There is clock that is generated outside the SoC. It
  14. is expected that it is defined using standard clock bindings
  15. with following clock-output-name:
  16. - "fin_pll" - PLL input clock from XXTI
  17. Example 1: An example of a clock controller node is listed below.
  18. clock: clock-controller@0x10010000 {
  19. compatible = "samsung,exynos5410-clock";
  20. reg = <0x10010000 0x30000>;
  21. #clock-cells = <1>;
  22. };
  23. Example 2: UART controller node that consumes the clock generated by the clock
  24. controller. Refer to the standard clock bindings for information
  25. about 'clocks' and 'clock-names' property.
  26. serial@12C20000 {
  27. compatible = "samsung,exynos4210-uart";
  28. reg = <0x12C00000 0x100>;
  29. interrupts = <0 51 0>;
  30. clocks = <&clock CLK_UART0>, <&clock CLK_SCLK_UART0>;
  31. clock-names = "uart", "clk_uart_baud0";
  32. };
