* Samsung Exynos5410 Clock Controller
The Exynos5410 clock controller generates and supplies clock to various
controllers within the Exynos5410 SoC.
Required Properties:
- compatible: should be "samsung,exynos5410-clock"
- 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/exynos5410.h header and can be used in device
tree sources.
External clock:
There is clock that is generated outside the SoC. It
is expected that it is defined using standard clock bindings
with following clock-output-name:
- "fin_pll" - PLL input clock from XXTI
Example 1: An example of a clock controller node is listed below.
clock: clock-controller@0x10010000 {
compatible = "samsung,exynos5410-clock";
reg = <0x10010000 0x30000>;
#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@12C20000 {
compatible = "samsung,exynos4210-uart";
reg = <0x12C00000 0x100>;
interrupts = <0 51 0>;
clocks = <&clock CLK_UART0>, <&clock CLK_SCLK_UART0>;
clock-names = "uart", "clk_uart_baud0";
};
