1* Hisilicon Hi3670 Clock Controller2 3The Hi3670 clock controller generates and supplies clock to various4controllers within the Hi3670 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,hi3670-crgctrl"12 - "hisilicon,hi3670-pctrl"13 - "hisilicon,hi3670-pmuctrl"14 - "hisilicon,hi3670-sctrl"15 - "hisilicon,hi3670-iomcu"16 - "hisilicon,hi3670-media1-crg"17 - "hisilicon,hi3670-media2-crg"18 19- reg: physical base address of the controller and length of memory mapped20 region.21 22- #clock-cells: should be 1.23 24Each clock is assigned an identifier and client nodes use this identifier25to specify the clock which they consume.26 27All these identifier could be found in <dt-bindings/clock/hi3670-clock.h>.28 29Examples:30 crg_ctrl: clock-controller@fff35000 {31 compatible = "hisilicon,hi3670-crgctrl", "syscon";32 reg = <0x0 0xfff35000 0x0 0x1000>;33 #clock-cells = <1>;34 };35 36 uart0: serial@fdf02000 {37 compatible = "arm,pl011", "arm,primecell";38 reg = <0x0 0xfdf02000 0x0 0x1000>;39 interrupts = <GIC_SPI 74 IRQ_TYPE_LEVEL_HIGH>;40 clocks = <&crg_ctrl HI3670_CLK_GATE_UART0>,41 <&crg_ctrl HI3670_PCLK>;42 clock-names = "uartclk", "apb_pclk";43 };44
