Hello!!!
I have completed the device tree overlay of the max98090 audio codec. I also got the widgets in the taskbar and audio card created. I'm posting the code here.
Thank you @aBUGSworstnightmare for helping me through the debugging process!
max98090.dtsSound cardTo test if the audio is getting captured and playedI2C bus is being used by the overlay.Driver and overlay verification.Compiling steps,Thanks!
