clk: exynos4: register clocks using common clock framework
The Exynos4 clocks are statically listed and registered using the Samsung specific common clock helper functions. Both device tree based clock lookup and clkdev based clock lookups are supported.

* 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:
|
||||
|
||||
- comptible: 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.
|
||||
|
||||
The following is the list of clocks generated by the controller. Each clock is
|
||||
assigned an identifier and client nodes use this identifier to specify the
|
||||
clock which they consume. Some of the clocks are available only on a particular
|
||||
Exynos4 SoC and this is specified where applicable.

compatible = "samsung,exynos4210-clock";

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 314>, <&clock 153>;
|
||||
clock-names = "uart", "clk_uart_baud0";
|
||||
};
