-* Samsung Exynos5410 Clock Controller
-
-The Exynos5410 clock controller generates and supplies clock to various
-controllers within the Exynos5410 SoC.
-
-Required Properties:
-
-- compatible: should be "samsung,exynos5410-clock"
-
-- reg: physical base address of the controller and length of memory mapped
-  region.
-
-- #clock-cells: should be 1.
-
-- clocks: should contain an entry specifying the root clock from external
-  oscillator supplied through XXTI or XusbXTI pin.  This clock should be
-  defined using standard clock bindings with "fin_pll" clock-output-name.
-  That clock is being passed internally to the 9 PLLs.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5410.h header and can be used in device
-tree sources.
-
-Example 1: An example of a clock controller node is listed below.
-
-	fin_pll: xxti {
-		compatible = "fixed-clock";
-		clock-frequency = <24000000>;
-		clock-output-names = "fin_pll";
-		#clock-cells = <0>;
-	};
-
-	clock: clock-controller@10010000 {
-		compatible = "samsung,exynos5410-clock";
-		reg = <0x10010000 0x30000>;
-		#clock-cells = <1>;
-		clocks = <&fin_pll>;
-	};
-
-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@12c20000 {
-		compatible = "samsung,exynos4210-uart";
-		reg = <0x12C00000 0x100>;
-		interrupts = <0 51 0>;
-		clocks = <&clock CLK_UART0>, <&clock CLK_SCLK_UART0>;
-		clock-names = "uart", "clk_uart_baud0";
-	};
