Freescale Sony/Philips Digital Interface Format (S/PDIF) Controller
The Freescale S/PDIF audio block is a stereo transceiver that allows the
processor to receive and transmit digital audio via an coaxial cable or
a fibre cable.
Required properties:
- compatible : Compatible list, must contain "fsl,imx35-spdif".
- reg : Offset and length of the register set for the device.
- interrupts : Contains the spdif interrupt.
- dmas : Generic dma devicetree binding as described in
- 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:
"core" The core clock of spdif controller
"rxtx<0-7>" Clock source list for tx and rx clock.
This clock list should be identical to
the source list connecting to the spdif
clock mux in "SPDIF Transceiver Clock
Diagram" of SoC reference manual. It
can also be referred to TxClk_Source
bit of register SPDIF_STC.
