   1 Allwinner A10 SPI controller
   2
   3 Required properties:
   4 - compatible: Should be "allwinner,sun4-a10-spi".
   5 - reg: Should contain register location and length.
   6 - interrupts: Should contain interrupt.
   7 - clocks: phandle to the clocks feeding the SPI controller. Two are
   8           needed:
   9   - "ahb": the gated AHB parent clock
  10   - "mod": the parent module clock
  11 - clock-names: Must contain the clock names described just above

  13 Example:
  14
  15 spi1: spi@1c06000 {
  16         compatible = "allwinner,sun4i-a10-spi";
  17         reg = <0x01c06000 0x1000>;
  18         interrupts = <11>;
  19         clocks = <&ahb_gates 21>, <&spi1_clk>;
  20         clock-names = "ahb", "mod";
  21         #address-cells = <1>;
  22         #size-cells = <0>;
  23 };
