+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
- "allwinner,sun7i-a20-spdif": for the Allwinner A20 SoC
- "allwinner,sun6i-a31-spdif": for the Allwinner A31 SoC
Are all these compatibles really work? Is there any significant difference between the controller on all these SoCs?
Thanks, Maxime
