Required properties:
- compatible : Must be "zte,zx296702-i2s"
- compatible : Should include one of the following strings:
- "zte,zx296702-i2s","zte,zx296718-i2s".
- reg : Must contain I2S core's registers location and length
- clocks : Pairs of phandle and specifier referencing the controller's clocks.
- clock-names: "tx" for the clock to the I2S interface.
- clock-names: "tx" for the wclk, "pclk" for the pclk to the I2S interface.
- must contain pclk for zx296718 SoC.
The 'pclk' is really required for zx296702-i2s as well. The driver may happen to work on zx296702 only because 'pclk' is already enabled by someone else before I2S driver starts working.

- dmas: Pairs of phandle and specifier for the DMA channel that is used by the core. The core expects two dma channels for transmit.
- dma-names : Must be "tx" and "rx"
