15 This binding represents Ethernet Switches which have a dedicated CPU
16 port. That port is usually connected to an Ethernet Controller of the
17 SoC. Such setups are typical for embedded devices.
23 pattern: "^(ethernet-)?switch(@.*)?$"
29 A two element list indicates which DSA cluster, and position within the
30 cluster a switch takes. <0 0> is cluster 0, switch 0. <0 1> is cluster 0,
31 switch 1. <1 0> is cluster 1, switch 0. A switch not part of any cluster
32 (single device hanging off a CPU port) must not specify this property
