Subject: [PATCH v4 net-next 8/9] dt-bindings: net: add generic ethernet-switch-port binding
Date: Fri,  2 Dec 2022 12:45:58 -0800	[thread overview]
Message-ID: <20221202204559.162619-9-colin.foster@in-advantage.com> (raw)
In-Reply-To: <20221202204559.162619-1-colin.foster@in-advantage.com>

The dsa-port.yaml binding had several references that can be common to all
ethernet ports, not just dsa-specific ones. Break out the generic bindings
to ethernet-switch-port.yaml they can be used by non-dsa drivers.

v3 -> v4
  * Add Florian Reviewed tag

v2 -> v3
  * Change dsa-port title from "DSA Switch port Device Tree Bindings"
    to "Generic DSA Switch port"
  * Add reference to ethernet-switch-port.yaml# in dsa-port.yaml
  * Change title of ethernet-switch-port.yaml from "Ethernet Switch
    port Device Tree Bindings" to "Generic Ethernet Switch port"
  * Remove most properties from ethernet-switch-port.yaml. They're
    all in ethernet-controller, and are all allowed.
  * ethernet-switch.yaml now only references ethernet-switch-port.yaml#
    under the port node.

v1 -> v2
  * Remove accidental addition of
    "$ref: /schemas/net/ethernet-switch-port.yaml" which should be kept
    out of dsa-port so that it doesn't get referenced multiple times
    through both ethernet-switch and dsa-port.
