1ZTE ZX296702 I2S controller
2
3Required properties:
4 - compatible : Must be one of:
5	"zte,zx296718-i2s", "zte,zx296702-i2s"
6	"zte,zx296702-i2s"
7 - reg : Must contain I2S core's registers location and length
8 - clocks : Pairs of phandle and specifier referencing the controller's clocks.
9 - clock-names: "wclk" for the wclk, "pclk" for the pclk to the I2S interface.
10 - dmas: Pairs of phandle and specifier for the DMA channel that is used by
11   the core. The core expects two dma channels for transmit.
12 - dma-names : Must be "tx" and "rx"
