1* Hisilicon Hi3660 Clock Controller2 3The Hi3660 clock controller generates and supplies clock to various4controllers within the Hi3660 SoC.5 6Required Properties:7 8- compatible: the compatible should be one of the following strings to9 indicate the clock controller functionality.10 11 - "hisilicon,hi3660-crgctrl"12 - "hisilicon,hi3660-pctrl"13 - "hisilicon,hi3660-pmuctrl"14 - "hisilicon,hi3660-sctrl"15 - "hisilicon,hi3660-iomcu"16 - "hisilicon,hi3660-stub-clk"17 18- reg: physical base address of the controller and length of memory mapped19 region.20 21- #clock-cells: should be 1.22 23Optional Properties:24 25- mboxes: Phandle to the mailbox for sending message to MCU.26 (See: ../mailbox/hisilicon,hi3660-mailbox.txt for more info)27 28Each clock is assigned an identifier and client nodes use this identifier29to specify the clock which they consume.30 31All these identifier could be found in <dt-bindings/clock/hi3660-clock.h>.32 33Examples:34 crg_ctrl: clock-controller@fff35000 {35 compatible = "hisilicon,hi3660-crgctrl", "syscon";36 reg = <0x0 0xfff35000 0x0 0x1000>;37 #clock-cells = <1>;38 };39 40 uart0: serial@fdf02000 {41 compatible = "arm,pl011", "arm,primecell";42 reg = <0x0 0xfdf02000 0x0 0x1000>;43 interrupts = <GIC_SPI 74 IRQ_TYPE_LEVEL_HIGH>;44 clocks = <&crg_ctrl HI3660_CLK_MUX_UART0>,45 <&crg_ctrl HI3660_PCLK>;46 clock-names = "uartclk", "apb_pclk";47 };48
