got a driver ak4637 compiled and in the system, have made changes to the device tree, and now I need to know where the widgets get defined.

dmesg has good messages but then

Hello!

These widgets are defined in the driver. For example for the ak4671 I see these. So you need to update the audio-routing in device-tree with the correct widget name for the codec.
