  24 +
  25 +Required properties:
  26 +
  27 +- compatible : Should contain entries for this and backward compatible
  28 +  SHAM versions:
  29 +  - "ti,omap2-sham" for OMAP2 & OMAP3.
  30 +  - "ti,omap4-sham" for OMAP4 and AM33XX.
  31 +  Note that these two versions are incompatible.
  32 +- ti,hwmods: Name of the hwmod associated with the SHAM module
  33 +- reg : Offset and length of the register set for the module
  34 +- interrupts : the interrupt-specifier for the SHAM module.
  35 +
  36 +Optional properties:
  37 +- dmas: DMA specifiers for the rx dma. See the DMA client binding,
  38 +       Documentation/devicetree/bindings/dma/dma.txt
  39 +- dma-names: DMA request name. Should be "rx" if a dma is present.

  41 +Example:
  42 +       /* AM335x */
  43 +       sham: sham@53100000 {
