-* 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@...10000 {
- 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@...20000 {
- 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";
- };
