From 75b942df87eaae1ba28fee3a1a82bfe147bb51ae Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Thu, 28 Mar 2019 23:24:50 +0100 Subject: [PATCH] colibri_vf: fix ethernet by adding explicit phy node The implicit fallback mechanism for searching the whole MDIO bus for at least one PHY has been gone with the following commit b882005a18de ("drivers/net/fec: phy_init: remove redundant logic"). This lead to the Ethernet driver erroring out as follows: Net: Could not get PHY for FEC0: addr -19 eth-1: fec@400d1000 Colibri VFxx # dhcp Could not get PHY for FEC0: addr -19 Could not get PHY for FEC0: addr -19 Could not get PHY for FEC0: addr -19 Could not get PHY for FEC0: addr -19 No ethernet found. Could not get PHY for FEC0: addr -19 Colibri VFxx # This commit adds an explicit PHY node which makes it work again.
