   3Required 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
   9Optional properties:
  10- fsl,saif-master: phandle to the master SAIF.  It's only required for
  11  the slave SAIF.
  12
  13Note: Each SAIF controller should have an alias correctly numbered
  14in "aliases" node.

  16Example:
  17
  18aliases {
  19        saif0 = &saif0;
  20        saif1 = &saif1;
  21};
  22
  23saif0: saif@80042000 {
  24        compatible = "fsl,imx28-saif";
  25        reg = <0x80042000 2000>;
  26        interrupts = <59 80>;
  27        fsl,saif-dma-channel = <4>;
  28};
  29
  30saif1: 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};
