sound: PCM/I2S Digital Mic & SPDIF

[Muni Sekhar]

Hello all,

I’m having a Linux X86 machine and interfacing with Xilinx FPGA
endpoint over PCIe. FPGA endpoint supports various audio engines like
PCM/I2S ,Digital Mic & SPDIF.

I’m looking for any existing linux device driver to port it for my hardware.

Does the Linux kernel tree have any reference examples for these audio
engines which I can use for porting it to my hardware? If so can
someone please share your inputs on this.
