1*4882a593SmuzhiyunBindings for I2S controller built into xtfpga Xtensa bitstreams.
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: shall be "cdns,xtfpga-i2s".
5*4882a593Smuzhiyun- reg: memory region (address and length) with device registers.
6*4882a593Smuzhiyun- interrupts: interrupt for the device.
7*4882a593Smuzhiyun- clocks: phandle to the clk used as master clock. I2S bus clock
8*4882a593Smuzhiyun  is derived from it.
