1* Samsung Exynos5250 Clock Controller 2 3The Exynos5250 clock controller generates and supplies clock to various 4controllers within the Exynos5250 SoC. 5 6Required Properties: 7 8- compatible: should be one of the following. 9 - "samsung,exynos5250-clock" - controller compatible with Exynos5250 SoC. 10 11- reg: physical base address of the controller and length of memory mapped 12 region. 13 14- #clock-cells: should be 1. 15 16Each clock is assigned an identifier and client nodes can use this identifier 17to specify the clock which they consume. 18 19All available clocks are defined as preprocessor macros in 20dt-bindings/clock/exynos5250.h header and can be used in device 21tree sources. 22 23Example 1: An example of a clock controller node is listed below. 24 25 clock: clock-controller@10010000 { 26 compatible = "samsung,exynos5250-clock"; 27 reg = <0x10010000 0x30000>; 28 #clock-cells = <1>; 29 }; 30 31Example 2: UART controller node that consumes the clock generated by the clock 32 controller. Refer to the standard clock bindings for information 33 about 'clocks' and 'clock-names' property. 34 35 serial@13820000 { 36 compatible = "samsung,exynos4210-uart"; 37 reg = <0x13820000 0x100>; 38 interrupts = <0 54 0>; 39 clocks = <&clock CLK_UART2>, <&clock CLK_SCLK_UART2>; 40 clock-names = "uart", "clk_uart_baud0"; 41 }; 42
