Where to put the source of a DD of a custom hardware.

[Raphael Philipe]

Hi,

I'm developing a device driver to drive a specific custom hardware,
that is implemented in FPGA. Since it is an application specific
device driver, where (in witch folder) should I put Its source in my
local kernel source tree? Is there any guideline or best practice
about it?

This device driver is basically a character device, that copies stuff
from hardware to kernel space and then from user space.
