Thanks for the review.

The SoC has CAN controller too and hence I chose this node name to differentiate. A grep of canfd on sysfs would tell if the controller is enabled. The channels on "net" would still be named "canx".

I'll change it if you still feel "can@e66c0000" is more appropriate.

Thanks,
Ramesh
