* 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";
|
|
};
