- reg : Must contain SPDIF core's registers location and length
- clocks : Pairs of phandle and specifier referencing the controller's clocks.
- clock-names: "tx" for the clock to the SPDIF interface.
- dmas: Pairs of phandle and specifier for the DMA channel that is used by
the core. The core expects one dma channel for transmit.
- dma-names : Must be "tx"
