+The Allwinner S/PDIF audio block is a transceiver that allows the +processor to receive and transmit digital audio via an coaxial cable or +a fibre cable.
+Required properties:
- compatible : should be one of the following:
- "allwinner,sun4i-a10-spdif": for the Allwinner A10 SoC
- reg : Offset and length of the register set for the device.
- interrupts : Contains the spdif interrupt.
- dmas : Generic dma devicetree binding as described in
Documentation/devicetree/bindings/dma/dma.txt.
- dma-names : Two dmas have to be defined, "tx" and "rx".
- clocks : Contains an entry for each entry in clock-names.
- clock-names : Includes the following entries:
- "apb" clock for the spdif bus.
- "spdif" clock for spdif controller.
+Optional:
- spdif-in : Enable block for capturing an SPDIF signal.
- spdif-out : Enable block for transmitting an SPDIF signal.
Is that a generic property? What values can it hold?
Thanks, Maxime
