General :: How To Visualize Related Files In Kernel Source

Is there any way (or what is the best way) to visualize what specific files within a kernel source are inter-related, what files take priority over others, etc? For example, I want to trace from top to bottom the related kernel source files & actions that would be triggered by insertion into a headphone jack, and dig through the code as much as I'm able and try narrowing down the source of a problem. I can (and have) poked around in github, and understand how to compile the kernel, but don't quite have a grasp of the hierarchy of files, drivers, etc. within the source.

If there isn't a way to 'map' out a specific kernel source, any generic flowchart or 'map' created in general for visualizing the inter-relationships of source files within android kernels?

How to compile a kernel, pack into a boot.img, edit a ramdisk, etc., within the last few weeks, but this is a major roadblock in my understanding of kernel source code.
