  28 +Required properties:
  29 +
  30 +- compatible : Should contain entries for this and backward compatible
  31 +  SHAM versions:
  32 +  - "ti,omap2-sham" for OMAP2 & OMAP3.
  33 +  - "ti,omap4-sham" for OMAP4 and AM33XX.
  34 +  Note that these two versions are incompatible.
  35 +- ti,hwmods: Name of the hwmod associated with the SHAM module
  36 +- reg : Offset and length of the register set for the module
  37 +- interrupts : the interrupt-specifier for the SHAM module.
  38 +
  39 +Optional properties:
  40 +- dmas: DMA specifiers for the rx dma. See the DMA client binding,
  41 +       Documentation/devicetree/bindings/dma/dma.txt
  42 +- dma-names: DMA request name. Should be "rx" if a dma is present.
