[PATCH net-next v2 1/2] dt-bindings: net: Add Maxio MAE0621A PHY
From: Liu Changjie <hidden>
Date: 2026-07-17 03:43:55

lkml, netdev
Subsystem:
networking drivers, open firmware and flattened device tree bindings, the rest · Maintainers:

Document the MAE0621A PHY ID and its optional 125 MHz CLKOUT setting. Boards which do not provide the property retain the hardware strap or bootloader configuration. Only the 125 MHz setting is exposed because it is the only setting exercised on hardware.
