DesignWare I2S controller Required properties: - compatible : Must be "snps,designware-i2s" - reg : Must contain the I2S core's registers location and length - clocks : Pairs of phandle and specifier referencing the controller's clocks. The controller expects one clock: the clock used as the sampling rate reference clock sample. - clock-names : "i2sclk" 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 one or two dma channels: one for transmit and one for receive. - dma-names : "tx" for the transmit channel, "rx" for the receive channel. For more details on the 'dma', 'dma-names', 'clock' and 'clock-names' properties please check: * resource-names.txt * clock/clock-bindings.txt * dma/dma.txt Example: soc_i2s: i2s@7ff90000 { compatible = "snps,designware-i2s"; reg = <0x0 0x7ff90000 0x0 0x1000>; clocks = <&scpi_i2sclk 0>; clock-names = "i2sclk"; #sound-dai-cells = <0>; dmas = <&dma0 5>; dma-names = "tx"; };
