clk: exynos5250: register clocks using common clock framework
The Exynos5250 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 Exynos5250 Clock Controller
|
||||
|
||||
The Exynos5250 clock controller generates and supplies clock to various
|
||||
controllers within the Exynos5250 SoC.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- comptible: should be one of the following.
|
||||
- "samsung,exynos5250-clock" - controller compatible with Exynos5250 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.

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.
|
||||
|

|
||||
interrupts = <0 54 0>;
|
||||
clocks = <&clock 314>, <&clock 153>;
|
||||
clock-names = "uart", "clk_uart_baud0";
