-* Samsung Exynos4 Clock Controller
-
-The Exynos4 clock controller generates and supplies clock to various controllers
-within the Exynos4 SoC. The clock binding described here is applicable to all
-SoC's in the Exynos4 family.
-
-Required Properties:
-
-- compatible: should be one of the following.
- - "samsung,exynos4210-clock" - controller compatible with Exynos4210 SoC.
- - "samsung,exynos4412-clock" - controller compatible with Exynos4412 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.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos4.h header and can be used in device
-tree sources.
-
-Example 1: An example of a clock controller node is listed below.
-
- clock: clock-controller@10030000 {
- compatible = "samsung,exynos4210-clock";
- reg = <0x10030000 0x20000>;
- #clock-cells = <1>;
- };
-
-Example 2: 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' property.
-
- serial@13820000 {
- compatible = "samsung,exynos4210-uart";
- reg = <0x13820000 0x100>;
- interrupts = <0 54 0>;
- clocks = <&clock CLK_UART2>, <&clock CLK_SCLK_UART2>;
- clock-names = "uart", "clk_uart_baud0";
- };
-
-Exynos4412 SoC contains some additional clocks for FIMC-ISP (Camera ISP)
-subsystem. Registers for those clocks are located in the ISP power domain.
-Because those registers are also located in a different memory region than
-the main clock controller, a separate clock controller has to be defined for
-handling them.
-
-Required Properties:
-
-- compatible: should be "samsung,exynos4412-isp-clock".
-
-- reg: physical base address of the ISP clock controller and length of memory
- mapped region.
-
-- #clock-cells: should be 1.
-
-- clocks: list of the clock controller input clock identifiers,
- from common clock bindings, should point to CLK_ACLK200 and
- CLK_ACLK400_MCUISP clocks from the main clock controller.
-
-- clock-names: list of the clock controller input clock names,
- as described in clock-bindings.txt, should be "aclk200" and
- "aclk400_mcuisp".
-
-- power-domains: a phandle to ISP power domain node as described by
- generic PM domain bindings.
-
-Example 3: The clock controllers bindings for Exynos4412 SoCs.
-
- clock: clock-controller@10030000 {
- compatible = "samsung,exynos4412-clock";
- reg = <0x10030000 0x18000>;
- #clock-cells = <1>;
- };
-
- isp_clock: clock-controller@10048000 {
- compatible = "samsung,exynos4412-isp-clock";
- reg = <0x10048000 0x1000>;
- #clock-cells = <1>;
- power-domains = <&pd_isp>;
- clocks = <&clock CLK_ACLK200>, <&clock CLK_ACLK400_MCUISP>;
- clock-names = "aclk200", "aclk400_mcuisp";
- };
