   1 Allwinner Clock Control Unit Binding
   2 ------------------------------------
   3
   4 Required properties :
   5 - compatible: must contain one of the following compatibles:
   6                 - "allwinner,sun6i-a31-ccu"
   7                 - "allwinner,sun8i-a23-ccu"
   8                 - "allwinner,sun8i-a33-ccu"
   9                 - "allwinner,sun8i-h3-ccu"
  10
  11 - reg: Must contain the registers base address and length
  12 - clocks: phandle to the oscillators feeding the CCU. Two are needed:
  13   - "hosc": the high frequency oscillator (usually at 24MHz)
  14   - "losc": the low frequency oscillator (usually at 32kHz)
  15 - clock-names: Must contain the clock names described just above
  16 - #clock-cells : must contain 1
  17 - #reset-cells : must contain 1
  18
  19 Example:
  20 ccu: clock@01c20000 {
  21         compatible = "allwinner,sun8i-h3-ccu";
  22         reg = <0x01c20000 0x400>;
  23         clocks = <&osc24M>, <&osc32k>;
  24         clock-names = "hosc", "losc";
  25         #clock-cells = <1>;
  26         #reset-cells = <1>;
  27 };
