1* Samsung Exynos5420 Clock Controller
2
3The Exynos5420 clock controller generates and supplies clock to various
4controllers within the Exynos5420 SoC.
5
6Required Properties:
7
8- comptible: should be one of the following.
9 - "samsung,exynos5420-clock" - controller compatible with Exynos5420 SoC.
10
11- reg: physical base address of the controller and length of memory mapped
12 region.
13
14- #clock-cells: should be 1.
15
16The following is the list of clocks generated by the controller. Each clock is
17assigned an identifier and client nodes use this identifier to specify the
18clock which they consume.

195Example 1: An example of a clock controller node is listed below.
196
197 clock: clock-controller@0x10010000 {
198 compatible = "samsung,exynos5420-clock";
199 reg = <0x10010000 0x30000>;
200 #clock-cells = <1>;
201 };
202
203Example 2: UART controller node that consumes the clock generated by the clock
204 controller. Refer to the standard clock bindings for information
205 about 'clocks' and 'clock-names' property.
206
207 serial@13820000 {
208 compatible = "samsung,exynos4210-uart";
209 reg = <0x13820000 0x100>;
210 interrupts = <0 54 0>;
211 clocks = <&clock 259>, <&clock 130>;
212 clock-names = "uart", "clk_uart_baud0";
213 };
