Some switch may require to add additional binding to the node port. Move DSA generic port definition to a dedicated yaml to permit this. Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

This binding represents Ethernet Switches which have a dedicated CPU
|
|
port. That port is usually connected to an Ethernet Controller of the
|
|
SoC. Such setups are typical for embedded devices.

A two element list indicates which DSA cluster, and position within the
|
|
cluster a switch takes. <0 0> is cluster 0, switch 0. <0 1> is cluster 0,
|
|
switch 1. <1 0> is cluster 1, switch 0. A switch not part of any cluster
|
|
(single device hanging off a CPU port) must not specify this property
