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. -- Thanks, Sekhar
