-* 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";
-       };
