+* 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.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/exynos5410.h header and can be used in device
+tree sources.
+
+External clock:
+There is clock that is generated outside the SoC. It is expected
+that it is defined using standard clock bindings with following
+ - compatible: should be "samsung,exynos5410-oscclk"
+
+Example 1: An example of a clock controller node is listed below.
+
+ clock: clock-controller@0x1001 {
+ compatible = "samsung,exynos5410-clock";
+ reg = <0x1001 0x3>;
+ #clock-cells = <1>;
+ };
+
+Example 2: Required external clock.
+
+ fixed-rate-clocks {
+ oscclk {
+ compatible = "samsung,exynos5410-oscclk";
+ clock-frequency = <2400>;
+ };
+ };
+
+Example 3: 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@12C2 {
+ compatible = "samsung,exynos4210-uart";
+ reg = <0x12C0 0x100>;
+ interrupts = <0 51 0>;
+ clocks = < CLK_UART0>, < CLK_SCLK_UART0>;
+ clock-names = "uart", "clk_uart_baud0";
+ };
