ADI AXI-SPDIF controller
|
|
|
|
Required properties:
|
|
- compatible : Must be "adi,axi-spdif-tx-1.00.a"
|
|
- reg : Must contain SPDIF core's registers location and length
|
|
- clocks : Pairs of phandle and specifier referencing the controller's clocks.
|
|
The controller expects two clocks, the clock used for the AXI interface and
|
|
the clock used as the sampling rate reference clock sample.
|
|
- clock-names: "axi" for the clock to the AXI interface, "ref" for the sample
|
|
rate reference clock.
|
|
- 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"
|
|
|
|
