1 Allwinner Sony/Philips Digital Interface Format (S/PDIF) Controller
3 The Allwinner S/PDIF audio block is a transceiver that allows the
4 processor to receive and transmit digital audio via an coaxial cable or
6 For now only playback is supported.
10 - compatible : should be one of the following:
11 - "allwinner,sun4i-a10-spdif": for the Allwinner A10 SoC
12 - "allwinner,sun6i-a31-spdif": for the Allwinner A31 SoC
13 - "allwinner,sun8i-h3-spdif": for the Allwinner H3 SoC
15 - reg : Offset and length of the register set for the device.
17 - interrupts : Contains the spdif interrupt.
19 - dmas : Generic dma devicetree binding as described in
20 Documentation/devicetree/bindings/dma/dma.txt.
22 - dma-names : Two dmas have to be defined, "tx" and "rx".
24 - clocks : Contains an entry for each entry in clock-names.
26 - clock-names : Includes the following entries:
27 "apb" clock for the spdif bus.
28 "spdif" clock for spdif controller.
30 - resets : reset specifier for the ahb reset (A31 and newer only)
