   3 Required properties:
   4 - compatible: Should be "fsl,<chip>-saif"
   5 - reg: Should contain registers location and length
   6 - interrupts: Should contain ERROR interrupt number
   7 - dmas: DMA specifier, consisting of a phandle to DMA controller node
   8   and SAIF DMA channel ID.
   9   Refer to dma.txt and fsl-mxs-dma.txt for details.
  10 - dma-names: Must be "rx-tx".
  11
  12 Optional properties:
  13 - fsl,saif-master: phandle to the master SAIF.  It's only required for
  14   the slave SAIF.
  15
  16 Note: Each SAIF controller should have an alias correctly numbered
  17 in "aliases" node.

  19 Example:
  20
  21 aliases {
  22         saif0 = &saif0;
  23         saif1 = &saif1;
  24 };
  25
  26 saif0: saif@80042000 {
  27         compatible = "fsl,imx28-saif";
  28         reg = <0x80042000 2000>;
  29         interrupts = <59>;
  30         dmas = <&dma_apbx 4>;
  31         dma-names = "rx-tx";
  32 };
  33
  34 saif1: saif@80046000 {
  35         compatible = "fsl,imx28-saif";
  36         reg = <0x80046000 2000>;
  37         interrupts = <58>;
  38         dmas = <&dma_apbx 5>;
  39         dma-names = "rx-tx";
  40         fsl,saif-master = <&saif0>;
  41 };
