[PATCH net-next 1/3] dt-bindings: net: ethernet-phy: add property mac-series-termination-ohms
From: Dimitri Fedrau via B4 Relay
Date: Fri Mar 07 2025 - 05:31:31 EST
From: Dimitri Fedrau <dimitri.fedrau@xxxxxxxxxxxx>
Add property mac-series-termination-ohms in the device tree bindings for
selecting the resistance value of the builtin series termination resistors
of the PHY. Changing the resistance to an appropriate value can reduce
signal reflections and therefore improve signal quality.
