-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>;
- };
