- * 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";
- };
