Required properties:

- reg : Must contain the I2S core's registers location and length
+ - interrupts: <IRQ> where IRQ is the interrupt number.
- 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.
