[PATCH v2 0/2] Add USB Ethernet controller (LAN7500) node in VAR-SOM-OM44 devicetree

[Thomas Richard]

In this second version I added LAN7500 and LAN7505 definitions in
microchip,lan95xx.yaml as requested by Krzysztof. I also added Nicolai's RB
tag in devicetree patch.

Changes in v2:
- add Nicolai's RB tag in patch 2/2.
- add LAN7500 and LAN7505 in microchip,lan95xx.yaml instead of creating a
  new file.
- Link to v1: https://lore.kernel.org/r/20260403-b4-var-som-om44-lan7500-v1-0-0dadde850143@bootlin.com
