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
|
||
|
|
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.
|
||
|
|
|
||
|
|
- 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@02004000 {
|
||
|
|
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",
