Recently, i began developing a driver of an embedded device running linux.

Until now i have only read about linux internals.
Having no prior experience in driver devlopment, i am finding it a tad difficult to land my first step.

• I have downloaded the kernel source-code (v2.6.32).
• I have read (skimped) Linux Device Drivers (3e)
• I read a few related posts here on StackOverflow.
• I understand that linux has a "monolithic" approach.
• I have built kernel (included existing driver in menuconfig etc.)
• I know the basics of kconfig and makefile files so that should not be a problem.

Can someone describe the structure (i.e. the inter-links)
of the various folders in the kernel-source code.

In other words given a source-code file,
which other files would it refer to for related code

(The "#include"-s provide a partial idea)

Could someone please help me in getting a better idea?
Any help will be greatly appreciated

Thank You.
