Not really, only 3-10 lines of code need to be added to the driver.

I've documented it a number of times in the linux-kernel archives.
Basically you need to add a class_simple structure, and add devices to
that structure when needed.  See the drivers/base/class_simple.c code
for information on the API, and any of the drivers that use that
interface for examples of how to use it (like drivers/char/misc.c or
drivers/char/mem.c).

Hope this helps,
