Device-Tree bindings for Xilinx I2S PL block
|
|
|
|
The IP supports I2S based playback/capture audio
|
|
|
|
Required property:
|
|
- compatible: "xlnx,i2s-transmitter-1.0" for playback and
|
|
"xlnx,i2s-receiver-1.0" for capture
|
|
|
|
Required property common to both I2S playback and capture:
|
|
- reg: Base address and size of the IP core instance.
|
|
- xlnx,dwidth: sample data width. Can be any of 16, 24.
|
|
- xlnx,num-channels: Number of I2S streams. Can be any of 1, 2, 3, 4.
|
|
supported channels = 2 * xlnx,num-channels
|
|
|
|
Example:
|
|
|
|
i2s_receiver@a0080000 {
|
|
compatible = "xlnx,i2s-receiver-1.0";
|
|
reg = <0x0 0xa0080000 0x0 0x10000>;
|
|
xlnx,dwidth = <0x18>;
|
|
xlnx,num-channels = <1>;
|
|
};
|
|
i2s_transmitter@a0090000 {
|
|
compatible = "xlnx,i2s-transmitter-1.0";
|
|
reg = <0x0 0xa0090000 0x0 0x10000>;
|
|
xlnx,dwidth = <0x18>;
|
|
xlnx,num-channels = <1>;
|
|
};
