Subject: [PATCH v3 net-next 08/10] dt-bindings: net: add generic ethernet-switch
The dsa.yaml bindings had references that can apply to non-dsa switches. To
prevent duplication of this information, keep the dsa-specific information
inside dsa.yaml and move the remaining generic information to the newly
created ethernet-switch.yaml.
Signed-off-by: Colin Foster <colin.foster@...advantage.com>
Suggested-by: Vladimir Oltean <olteanv@...il.com>
---
v2 -> v3
* Change ethernet-switch.yaml title from "Ethernet Switch Device
Tree Bindings" to "Generic Ethernet Switch"
* Rework ethernet-switch.yaml description
* Add base defs structure for switches that don't have any additional
properties.
* Add "additionalProperties: true" under "^(ethernet-)?ports$" node
* Correct port reference from /schemas/net/dsa/dsa-port.yaml# to
ethernet-controller.yaml#
v1 -> v2
* No net change, but deletions from dsa.yaml included the changes for
"addionalProperties: true" under ports and "unevaluatedProperties:
true" under port.

+description:
+ Ethernet switches are multi-port Ethernet controllers. Each port has
+ its own number and is represented as its own Ethernet controller.
+ The minimum required functionality is to pass packets to software.
+ They may or may not be able to forward packets automonously between
+ ports.
