   3 Required properties:
   4 - compatible: Should be "fsl,<chip>-saif"
   5 - reg: Should contain registers location and length
   6 - interrupts: Should contain ERROR and DMA interrupts
   7 - fsl,saif-dma-channel: APBX DMA channel for the SAIF
   8
   9 Optional properties:
  10 - fsl,saif-master: phandle to the master SAIF.  It's only required for
  11   the slave SAIF.
  12
  13 Note: Each SAIF controller should have an alias correctly numbered
  14 in "aliases" node.

  16 Example:
  17
  18 aliases {
  19         saif0 = &saif0;
  20         saif1 = &saif1;
  21 };
  22
  23 saif0: saif@80042000 {
  24         compatible = "fsl,imx28-saif";
  25         reg = <0x80042000 2000>;
  26         interrupts = <59 80>;
  27         fsl,saif-dma-channel = <4>;
  28 };
  29
  30 saif1: saif@80046000 {
  31         compatible = "fsl,imx28-saif";
  32         reg = <0x80046000 2000>;
  33         interrupts = <58 81>;
  34         fsl,saif-dma-channel = <5>;
  35         fsl,saif-master = <&saif0>;
  36 };
