-* Samsung S5P6442/S5PC110/S5PV210 Clock Controller
-
-Samsung S5P6442, S5PC110 and S5PV210 SoCs contain integrated clock
-controller, which generates and supplies clock to various controllers
-within the SoC.
-
-Required Properties:
-
-- compatible: should be one of following:
- - "samsung,s5pv210-clock" : for clock controller of Samsung
- S5PC110/S5PV210 SoCs,
- - "samsung,s5p6442-clock" : for clock controller of Samsung
- S5P6442 SoC.
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- #clock-cells: should be 1.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/s5pv210.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:
- - "xxti": external crystal oscillator connected to XXTI and XXTO pins of
-the SoC,
- - "xusbxti": external crystal oscillator connected to XUSBXTI and XUSBXTO
-pins of the SoC,
-
-A subset of above clocks available on given board shall be specified in
-board device tree, including the system base clock, as selected by XOM[0]
-pin of the SoC. Refer to generic fixed rate clock bindings
-documentation[1] for more information how to specify these clocks.
-
-[1] Documentation/devicetree/bindings/clock/fixed-clock.yaml
-
-Example: Clock controller node:
-
- clock: clock-controller@7e00f000 {
- compatible = "samsung,s5pv210-clock";
- reg = <0x7e00f000 0x1000>;
- #clock-cells = <1>;
- };
-
-Example: Required external clocks:
-
- xxti: clock-xxti {
- compatible = "fixed-clock";
- clock-output-names = "xxti";
- clock-frequency = <24000000>;
- #clock-cells = <0>;
- };
-
- xusbxti: clock-xusbxti {
- compatible = "fixed-clock";
- clock-output-names = "xusbxti";
- clock-frequency = <24000000>;
- #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@e2900000 {
- compatible = "samsung,s5pv210-uart";
- reg = <0xe2900000 0x400>;
- interrupt-parent = <&vic1>;
- interrupts = <10>;
- clock-names = "uart", "clk_uart_baud0",
- "clk_uart_baud1";
- clocks = <&clocks UART0>, <&clocks UART0>,
- <&clocks SCLK_UART0>;
- };
