CAN drivers can be found here;
http://lxr.free-electrons.com/source/drivers/net/can/

The device driver interface is at dev.c

AFAIK the only other files referencing to can outside of drivers/ folder is
http://lxr.free-electrons.com/source/include/uapi/linux/if_ether.h#L120
You may want to look at docs too:
https://www.kernel.org/doc/Documentation/networking/can.txt
