   2
   3 Required properties:
   4
   5 - compatible:
   6   "marvell,kirkwood-audio" for Kirkwood platforms
   7   "marvell,dove-audio" for Dove platforms
   8   "marvell,armada370-audio" for Armada 370 platforms
   9
  10 - reg: physical base address of the controller and length of memory mapped
  11   region.
  12
  13 - interrupts:
  14   with "marvell,kirkwood-audio", the audio interrupt
  15   with "marvell,dove-audio", a list of two interrupts, the first for
  16   the data flow, and the second for errors.
  17
  18 - clocks: one or two phandles.
  19   The first one is mandatory and defines the internal clock.
  20   The second one is optional and defines an external clock.
  21
  22 - clock-names: names associated to the clocks:
  23         "internal" for the internal clock
  24         "extclk" for the external clock
  25
  26 Example:
  27
  28 i2s1: audio-controller@b4000 {
  29         compatible = "marvell,dove-audio";
  30         reg = <0xb4000 0x2210>;
  31         interrupts = <21>, <22>;
  32         clocks = <&gate_clk 13>;
  33         clock-names = "internal";
  34 };
