-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, should contain one of the following
- compatibles:
- "fsl,imx35-spdif",
- "fsl,vf610-spdif",
- "fsl,imx6sx-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
- 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:
- "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.
- "spba" The spba clock is required when SPDIF is placed as a
- bus slave of the Shared Peripheral Bus and when two
- or more bus masters (CPU, DMA or DSP) try to access
- it. This property is optional depending on the SoC
- design.
-
-Optional properties:
-
- - big-endian : If this property is absent, the native endian mode
- will be in use as default, or the big endian mode
- will be in use for all the device registers.
-
-Example:
-
-spdif: spdif@2004000 {
- compatible = "fsl,imx35-spdif";
- reg = <0x02004000 0x4000>;
- interrupts = <0 52 0x04>;
- dmas = <&sdma 14 18 0>,
- <&sdma 15 18 0>;
- dma-names = "rx", "tx";
-
- clocks = <&clks 197>, <&clks 3>,
- <&clks 197>, <&clks 107>,
- <&clks 0>, <&clks 118>,
- <&clks 62>, <&clks 139>,
- <&clks 0>;
- clock-names = "core", "rxtx0",
- "rxtx1", "rxtx2",
- "rxtx3", "rxtx4",
- "rxtx5", "rxtx6",
- "rxtx7";
-
- big-endian;
-};
