-* 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.
- - "samsung,exynos3250-cmu-dmc" - controller compatible with
- Exynos3250 SoC for Dynamic Memory Controller domain.
- - "samsung,exynos3250-cmu-isp" - ISP block clock 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: Examples of clock controller nodes are listed below.
-
- cmu: clock-controller@10030000 {
- compatible = "samsung,exynos3250-cmu";
- reg = <0x10030000 0x20000>;
- #clock-cells = <1>;
- };
-
- cmu_dmc: clock-controller@105c0000 {
- compatible = "samsung,exynos3250-cmu-dmc";
- reg = <0x105C0000 0x2000>;
- #clock-cells = <1>;
- };
-
- cmu_isp: clock-controller@10048000 {
- compatible = "samsung,exynos3250-cmu-isp";
- reg = <0x10048000 0x1000>;
- #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";
- };
