1	* Samsung Exynos5410 Clock Controller
2	
3	The Exynos5410 clock controller generates and supplies clock to various
4	controllers within the Exynos5410 SoC.
5	
6	Required Properties:
7	
8	- compatible: should be "samsung,exynos5410-clock"
9	
10	- reg: physical base address of the controller and length of memory mapped
11	  region.
12	
13	- #clock-cells: should be 1.
14	
15	All available clocks are defined as preprocessor macros in
16	dt-bindings/clock/exynos5410.h header and can be used in device
17	tree sources.
18	
19	External clock:
20	
21	There is clock that is generated outside the SoC. It
22	is expected that it is defined using standard clock bindings
23	with following clock-output-name:
24	
25	 - "fin_pll" - PLL input clock from XXTI
26	
27	Example 1: An example of a clock controller node is listed below.
28	
29		clock: clock-controller@0x10010000 {
30			compatible = "samsung,exynos5410-clock";
31			reg = <0x10010000 0x30000>;
32			#clock-cells = <1>;
33		};
34	
35	Example 2: UART controller node that consumes the clock generated by the clock
36		   controller. Refer to the standard clock bindings for information
37		   about 'clocks' and 'clock-names' property.
38	
39		serial@12C20000 {
40			compatible = "samsung,exynos4210-uart";
41			reg = <0x12C00000 0x100>;
42			interrupts = <0 51 0>;
43			clocks = <&clock CLK_UART0>, <&clock CLK_SCLK_UART0>;
44			clock-names = "uart", "clk_uart_baud0";
45		};
