Kernel-4.18.0-80.el8_hi3660-clock

  • Hisilicon Hi3660 Clock Controller

The Hi3660 clock controller generates and supplies clock to various
controllers within the Hi3660 SoC.

Required Properties:

  • compatible: the compatible should be one of the following strings to
    indicate the clock controller functionality.

    • “hisilicon,hi3660-crgctrl”
    • “hisilicon,hi3660-pctrl”
    • “hisilicon,hi3660-pmuctrl”
    • “hisilicon,hi3660-sctrl”
    • “hisilicon,hi3660-iomcu”
    • “hisilicon,hi3660-stub-clk”
  • reg: physical base address of the controller and length of memory mapped
    region.

  • #clock-cells: should be 1.

Optional Properties:

  • mboxes: Phandle to the mailbox for sending message to MCU.
          (See: ../mailbox/hisilicon,hi3660-mailbox.txt for more info)
    

Each clock is assigned an identifier and client nodes use this identifier
to specify the clock which they consume.

All these identifier could be found in <dt-bindings/clock/hi3660-clock.h>.

Examples:
crg_ctrl: clock-controller@fff35000 {
compatible = “hisilicon,hi3660-crgctrl”, “syscon”;
reg = <0x0 0xfff35000 0x0 0x1000>;
#clock-cells = <1>;
};

uart0: serial@fdf02000 {
    compatible = "arm,pl011", "arm,primecell";
    reg = <0x0 0xfdf02000 0x0 0x1000>;
    interrupts = <GIC_SPI 74 IRQ_TYPE_LEVEL_HIGH>;
    clocks = <&crg_ctrl HI3660_CLK_MUX_UART0>,
         <&crg_ctrl HI3660_PCLK>;
    clock-names = "uartclk", "apb_pclk";
};
