[PATCH v6 0/3] document dt-schema for some USB Ethernet controllers

[Oleksij Rempel]

changes v6:
- remove USB hub example from microchip,lan95xx.yaml. We care only about
  ethernet node.
- use only documented USD ID in example.
- add Reviewed-by
- drop board patches, all of them are taken by different subsystem
  maintainers.

changes v5:
- move compatible string changes to a separate patch
- add note about possible regressions

changes v4:
- reword commit logs.
- add note about compatible fix

Oleksij Rempel (3):
  dt-bindings: net: add schema for ASIX USB Ethernet controllers
  dt-bindings: net: add schema for Microchip/SMSC LAN95xx USB Ethernet
    controllers
  dt-bindings: usb: ci-hdrc-usb2: fix node node for ethernet controller

[PATCH v6 1/3] dt-bindings: net: add schema for ASIX USB Ethernet controllers

[Oleksij Rempel]

Create schema for ASIX USB Ethernet controllers and import some of
currently supported USB IDs form drivers/net/usb/asix_devices.c

These devices are already used in some of DTs. So, this schema makes it official.
NOTE: there was no previously documented txt based DT binding for this
controllers.

[Oleksij Rempel]

import some of currently supported USB IDs form drivers/net/usb/smsc95xx.c

These devices are already used in some of DTs. So, this schema makes it official.
NOTE: there was no previously documented txt based DT binding for this

[PATCH v6 3/3] dt-bindings: usb: ci-hdrc-usb2: fix node node for ethernet controller

[Oleksij Rempel]

This documentation provides wrong node name for the Ethernet controller.
It should be "ethernet" instead of "smsc" as required by Ethernet
controller devicetree schema:
 Documentation/devicetree/bindings/net/ethernet-controller.yaml
