1 * Samsung S3C64xx Clock Controller
3 The S3C64xx clock controller generates and supplies clock to various controllers
4 within the SoC. The clock binding described here is applicable to all SoCs in
5 the S3C64xx family.
9 - compatible: should be one of the following.
10   - "samsung,s3c6400-clock" - controller compatible with S3C6400 SoC.
11   - "samsung,s3c6410-clock" - controller compatible with S3C6410 SoC.
13 - reg: physical base address of the controller and length of memory mapped
16 - #clock-cells: should be 1.
18 Each clock is assigned an identifier and client nodes can use this identifier
19 to specify the clock which they consume. Some of the clocks are available only
20 on a particular S3C64xx SoC and this is specified where applicable.
23 dt-bindings/clock/samsung,s3c64xx-clock.h header and can be used in device
29 that they are defined using standard clock bindings with following
30 clock-output-names:
31  - "fin_pll" - PLL input clock (xtal/extclk) - required,
32  - "xusbxti" - USB xtal - required,
33  - "iiscdclk0" - I2S0 codec clock - optional,
34  - "iiscdclk1" - I2S1 codec clock - optional,
35  - "iiscdclk2" - I2S2 codec clock - optional,
36  - "pcmcdclk0" - PCM0 codec clock - optional,
37  - "pcmcdclk1" - PCM1 codec clock - optional, only S3C6410.
39 Example: Clock controller node:
41 	clock: clock-controller@7e00f000 {
42 		compatible = "samsung,s3c6410-clock";
44 		#clock-cells = <1>;
49 	fin_pll: clock-fin-pll {
50 		compatible = "fixed-clock";
51 		clock-output-names = "fin_pll";
52 		clock-frequency = <12000000>;
53 		#clock-cells = <0>;
56 	xusbxti: clock-xusbxti {
57 		compatible = "fixed-clock";
58 		clock-output-names = "xusbxti";
59 		clock-frequency = <48000000>;
60 		#clock-cells = <0>;
63 Example: UART controller node that consumes the clock generated by the clock
64   controller (refer to the standard clock bindings for information about
65   "clocks" and "clock-names" properties):
68 			compatible = "samsung,s3c6400-uart";
70 			interrupt-parent = <&vic1>;
72 			clock-names = "uart", "clk_uart_baud2",
74 			clocks = <&clock PCLK_UART0>, <&clocks PCLK_UART0>,
75 					<&clock SCLK_UART>;
