Looking at Documentation/devicetree/bindings/net/cpsw.txt, your DSA

Hi Andrew,
Yes, that's what sounds logical, however that node does not become the
parent device net class nodes:
root@r600:/sys/class/net# ls -l
[...]
lrwxrwxrwx 1 root root 0 Jan 1 1970 eth0 ->
../../devices/platform/ocp/4a100000.ethernet/net/eth0
lrwxrwxrwx 1 root root 0 Jan 1 1970 eth1 ->
../../devices/platform/ocp/4a100000.ethernet/net/eth1

root@r600:/sys/class/net# cd eth0
root@r600:/sys/devices/platform/ocp/4a100000.ethernet/net/eth0# ls -l

lrwxrwxrwx 1 root root 0 Jan 1 1970 device ->

IMHO it should be the CPSW driver that should istantiate two separate
devices, one for each cpsw_emacX node in the device tree.
Do you think they could be receptive to such proposal?
Thanks,
