1 DesignWare I2S controller
4 - compatible : Must be "snps,designware-i2s"
5 - reg : Must contain the I2S core's registers location and length
6 - clocks : Pairs of phandle and specifier referencing the controller's
7 clocks. The controller expects one clock: the clock used as the sampling
8 rate reference clock sample.
9 - clock-names : "i2sclk" for the sample rate reference clock.
10 - dmas: Pairs of phandle and specifier for the DMA channels that are used by
11 the core. The core expects one or two dma channels: one for transmit and
13 - dma-names : "tx" for the transmit channel, "rx" for the receive channel.
16 - interrupts: The interrupt line number for the I2S controller. Add this
17 parameter if the I2S controller that you are using does not support DMA.
