+* Samsung Exynos5420 Clock Controller
+
+The Exynos5420 clock controller generates and supplies clock to various
+controllers within the Exynos5420 SoC.
+
+Required Properties:
+
+- comptible: should be one of the following.
+ - "samsung,exynos5420-clock" - controller compatible with Exynos5420 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,exynos5420-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 259>, <&clock 130>;
+ clock-names = "uart", "clk_uart_baud0";
+ };
