Required properties for devices compatible with "atmel,at91sam9g45-ssc":

- dmas: DMA specifier, consisting of a phandle to DMA controller node,

  the memory interface and SSC DMA channel ID (for tx and rx).

  See Documentation/devicetree/bindings/dma/atmel-dma.txt for details.

- dma-names: Must be "tx", "rx".



Examples:

- PDC transfer:
