| - 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>;
