The Exynos3250 clocks are statically listed and registered using the
Samsung specific common clock helper functions. Both device tree based

+* Samsung Exynos3250 Clock Controller
+
+The Exynos3250 clock controller generates and supplies clock to various
+controllers within the Exynos3250 SoC.
+
+Required Properties:
+
+- compatible: should be one of the following.
+ - "samsung,exynos3250-cmu" - controller compatible with Exynos3250 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/exynos3250.h header and can be used in device
+tree sources.
+
+Example 1: An example of a clock controller node is listed below.
+
+ cmu: clock-controller@10030000 {
+ compatible = "samsung,exynos3250-cmu";
+ reg =<0x10030000 0x20000>;
+ #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@13800000 {
+ compatible = "samsung,exynos4210-uart";
+ reg =<0x13800000 0x100>;
+ interrupts =<0 109 0>;
+ clocks =<&cmu CLK_UART0>,<&cmu CLK_SCLK_UART0>;
+ clock-names = "uart", "clk_uart_baud0";
+ };
Oops, I've forgotten to apply this one. Since it doesn't have any
dependencies, Kukjin, could you apply it on top of my pull requests with
my Ack? Thanks in advance.

Sure, I will do it on your 4/4 pull-request after pulling it into
samsung tree.
Thanks,
Kukjin
