* 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";
};
