From 2bfab76f4c73536717f6c6cda2dcb2a60bb25ece Mon Sep 17 00:00:00 2001 From: Maksim Kiselev Date: Sat, 20 Jan 2024 19:26:24 +0300 Subject: [PATCH] net: sun8i-emac: Add support for fixed-link phy Make the "phy-handle" property optional, which allows support for a fixed-link phy configuration. Thus if the "phy-handle" is present in a DT, then driver will work as before. Otherwise, phyaddr initialization will not be necessary, as it is not needed in case of a fixed-link config.
