| 2 | |
| 3 | Required properties: |
| 4 | - compatible: shall be "cdns,xtfpga-i2s". |
| 5 | - reg: memory region (address and length) with device registers. |
| 6 | - interrupts: interrupt for the device. |
| 7 | - clocks: phandle to the clk used as master clock. I2S bus clock |
| 8 | is derived from it. |

| 10 | Examples: |
| 11 | |
| 12 | i2s0: xtfpga-i2s@0d080000 { |
| 13 | #sound-dai-cells = <0>; |
| 14 | compatible = "cdns,xtfpga-i2s"; |
| 15 | reg = <0x0d080000 0x40>; |
| 16 | interrupts = <2 1>; |
| 17 | clocks = <&cdce706 4>; |
| 18 | }; |
