  - #sound-dai-cells : Must be equal to 0

  - reg : Offset and length of the register set for the device

  - dmas: Contains an entry for each entry in dma-names.

  - dma-names: Must include the following entry:
	"tx"

  - clocks : Contains an entry for each entry in clock-names.

  - clock-names : Includes the following entries:
	"sys"	The system clock
	"ref"	The reference clock

  - resets: Contains a phandle to the spdif out reset signal

  - reset-names: Contains the reset signal name "rst"

Optional Properties:
