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) does not usually need to specify
this property, and then it becomes cluster 0, switch 0. For a topology
aware switch, its switch index can be specified through this property,
even if it is not part of any cluster. Also, topology-unaware switches
must always be defined as index 0 of their cluster.
