1* Samsung Exynos5440 Clock Controller 2 3The Exynos5440 clock controller generates and supplies clock to various 4controllers within the Exynos5440 SoC. 5 6Required Properties: 7 8- comptible: should be "samsung,exynos5440-clock". 9 10- reg: physical base address of the controller and length of memory mapped 11 region. 12 13- #clock-cells: should be 1. 14 15The following is the list of clocks generated by the controller. Each clock is 16assigned an identifier and client nodes use this identifier to specify the 17clock which they consume. 18 19 20 [Core Clocks] 21 22 Clock ID 23 ---------------------------- 24 25 xtal 1 26 arm_clk 2 27 28 [Peripheral Clock Gates] 29 30 Clock ID 31 ---------------------------- 32 33 spi_baud 16 34 pb0_250 17 35 pr0_250 18 36 pr1_250 19 37 b_250 20 38 b_125 21 39 b_200 22 40 sata 23 41 usb 24 42 gmac0 25 43 cs250 26 44 pb0_250_o 27 45 pr0_250_o 28 46 pr1_250_o 29 47 b_250_o 30 48 b_125_o 31 49 b_200_o 32 50 sata_o 33 51 usb_o 34 52 gmac0_o 35 53 cs250_o 36 54 55Example: An example of a clock controller node is listed below. 56 57 clock: clock-controller@0x10010000 { 58 compatible = "samsung,exynos5440-clock"; 59 reg = <0x160000 0x10000>; 60 #clock-cells = <1>; 61 }; 62
