   1 * Hisilicon Hi3670 Clock Controller
   2
   3 The Hi3670 clock controller generates and supplies clock to various
   4 controllers within the Hi3670 SoC.
   5
   6 Required Properties:
   7
   8 - compatible: the compatible should be one of the following strings to
   9         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 mapped
  20   region.
  21
  22 - #clock-cells: should be 1.
  23
  24 Each clock is assigned an identifier and client nodes use this identifier
  25 to specify the clock which they consume.
  26
  27 All these identifier could be found in <dt-bindings/clock/hi3670-clock.h>.

  29 Examples:
  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";
