description:
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.

description:
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
