Linux Kernel configs needed for ADAU1761 codec driver

Question

Hi, 
 I'm trying to add support for ADAU1761 codec in my linux build. Do I need to add the firmware(SigmaDSP firmware) file if I'm not using the DSP processor onboard? 
 To add support for codec is Enabling ADAU1761 codec driver in linux config and updating the device tree enough?

Hi, 
 SigmaDSP firmware is optional and ADAU1761 can be used as a simple codec without DSP. 
 You're right, to add support you have to enable the kernel driver (module or built-in) and add the devicetree bindings for ADAU1761. 
 For device-tree bindings we have examples for RPI , Xilinx Zynq and the Linux kernel devicetree documentation .
