1*4882a593SmuzhiyunZTE ZX296702 SPDIF controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun - compatible : Must be "zte,zx296702-spdif"
5*4882a593Smuzhiyun - reg : Must contain SPDIF core's registers location and length
6*4882a593Smuzhiyun - clocks : Pairs of phandle and specifier referencing the controller's clocks.
7*4882a593Smuzhiyun - clock-names: "tx" for the clock to the SPDIF interface.
8*4882a593Smuzhiyun - dmas: Pairs of phandle and specifier for the DMA channel that is used by
9*4882a593Smuzhiyun   the core. The core expects one dma channel for transmit.
10*4882a593Smuzhiyun - dma-names : Must be "tx"
