Yes, dcan is not supported in the yocto kernel. There do have dcan device
nodes in the beagle bone black dts but it is disabled by default. That is
why you can't find the dcan device after boot. In order to make dcan work,
I think you have to tweak a bit about the current dts file such as:
  - enable the dcan device node.
  - set the correct pinmux

Thanks,
Kevin
