   3 Required properties:
   4   - reg: Physical base address and size of the controller's register area.
   5   - compatible: Compatibility string. Must be 'fsl,<chip>-ahci', where
   6     chip could be ls1021a, ls2080a, ls1043a etc.
   7   - clocks: Input clock specifier. Refer to common clock bindings.
   8   - interrupts: Interrupt specifier. Refer to interrupt binding.

  14 Examples:
  15         sata@3200000 {
  16                 compatible = "fsl,ls1021a-ahci";
  17                 reg = <0x0 0x3200000 0x0 0x10000>;
  18                 interrupts = <GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>;
  19                 clocks = <&platform_clk 1>;
