Doesn't the huge number of example drivers in the kernel sources provide
a wonderful place to start with?

What specifically are you trying to do here that you need help with?

Nothing specific as such, I wanted to learn starting  from basic and
easy code. drivers/pci/ directory has lots of code but I dont know the
order. Is there any documentation? Some basic and small piece of code
for foundation purpose. If you can suggest me one.

Thank you,
Vijay

Don't pay attention to the drivers/pci/ directory, that is the code that
implements the PCI core, no driver needs to mess with that.  For an
introduction to writing a PCI driver, please see the (outdated, but
free) Linux Device Drivers, third edition book.

Good luck,
