1ADI AXI-I2S controller 2 3Required properties: 4 - compatible : Must be "adi,axi-i2s-1.00.a" 5 - reg : Must contain I2S core's registers location and length 6 - clocks : Pairs of phandle and specifier referencing the controller's clocks. 7 The controller expects two clocks, the clock used for the AXI interface and 8 the clock used as the sampling rate reference clock sample. 9 - clock-names : "axi" for the clock to the AXI interface, "ref" for the sample 10 rate reference clock. 11 - dmas: Pairs of phandle and specifier for the DMA channels that are used by 12 the core. The core expects two dma channels, one for transmit and one for 13 receive. 14 - dma-names : "tx" for the transmit channel, "rx" for the receive channel. 15 16For more details on the 'dma', 'dma-names', 'clock' and 'clock-names' properties 17please check: 18 * resource-names.txt 19 * clock/clock-bindings.txt 20 * dma/dma.txt 21 22Example: 23 24 i2s: i2s@0x77600000 { 25 compatible = "adi,axi-i2s-1.00.a"; 26 reg = <0x77600000 0x1000>; 27 clocks = <&clk 15>, <&audio_clock>; 28 clock-names = "axi", "ref"; 29 dmas = <&ps7_dma 0>, <&ps7_dma 1>; 30 dma-names = "tx", "rx"; 31 }; 32
