| ADI AXI-I2S controller |
| |
| Required properties: |
| - compatible : Must be "adi,axi-i2s-1.00.a" |
| - reg : Must contain I2S core's registers location and length |
| - clocks : Pairs of phandle and specifier referencing the controller's clocks. |
| The controller expects two clocks, the clock used for the AXI interface and |
| the clock used as the sampling rate reference clock sample. |
| - clock-names : "axi" for the clock to the AXI interface, "ref" for the sample |
| rate reference clock. |
| - dmas: Pairs of phandle and specifier for the DMA channels that are used by |
| the core. The core expects two dma channels, one for transmit and one for |
| receive. |
| - dma-names : "tx" for the transmit channel, "rx" for the receive channel. |
| |

| Example: |
| |
| i2s: i2s@77600000 { |
| compatible = "adi,axi-i2s-1.00.a"; |
| reg = <0x77600000 0x1000>; |
| clocks = <&clk 15>, <&audio_clock>; |
| clock-names = "axi", "ref"; |
| dmas = <&ps7_dma 0>, <&ps7_dma 1>; |
| dma-names = "tx", "rx"; |
| }; |
