-* Samsung S3C64xx Clock Controller
-
-The S3C64xx clock controller generates and supplies clock to various controllers
-within the SoC. The clock binding described here is applicable to all SoCs in
-the S3C64xx family.
-
-Required Properties:
-
-- compatible: should be one of the following.
- - "samsung,s3c6400-clock" - controller compatible with S3C6400 SoC.
- - "samsung,s3c6410-clock" - controller compatible with S3C6410 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. Some of the clocks are available only
-on a particular S3C64xx SoC and this is specified where applicable.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/samsung,s3c64xx-clock.h header and can be used in device
-tree sources.
-
-External clocks:
-
-There are several clocks that are generated outside the SoC. It is expected
-that they are defined using standard clock bindings with following
-clock-output-names:
- - "fin_pll" - PLL input clock (xtal/extclk) - required,
- - "xusbxti" - USB xtal - required,
- - "iiscdclk0" - I2S0 codec clock - optional,
- - "iiscdclk1" - I2S1 codec clock - optional,
- - "iiscdclk2" - I2S2 codec clock - optional,
- - "pcmcdclk0" - PCM0 codec clock - optional,
- - "pcmcdclk1" - PCM1 codec clock - optional, only S3C6410.
-
-Example: Clock controller node:
-
- clock: clock-controller@7e00f000 {
- compatible = "samsung,s3c6410-clock";
- reg = <0x7e00f000 0x1000>;
- #clock-cells = <1>;
- };
-
-Example: Required external clocks:
-
- fin_pll: clock-fin-pll {
- compatible = "fixed-clock";
- clock-output-names = "fin_pll";
- clock-frequency = <12000000>;
- #clock-cells = <0>;
- };
-
- xusbxti: clock-xusbxti {
- compatible = "fixed-clock";
- clock-output-names = "xusbxti";
- clock-frequency = <48000000>;
- #clock-cells = <0>;
- };
-
-Example: 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" properties):
-
- uart0: serial@7f005000 {
- compatible = "samsung,s3c6400-uart";
- reg = <0x7f005000 0x100>;
- interrupt-parent = <&vic1>;
- interrupts = <5>;
- clock-names = "uart", "clk_uart_baud2",
- "clk_uart_baud3";
- clocks = <&clock PCLK_UART0>, <&clocks PCLK_UART0>,
- <&clock SCLK_UART>;
- };
