From ff7944829497ce94feb62268d0652487ea873ac2 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Wed, 23 Feb 2022 16:17:40 +0100 Subject: [PATCH] arm64: zynqmp: Switch to ethernet-phy-id in kv260 Use ethernet-phy-id compatible string to properly describe phy reset on kv260 boards. Previous description wasn't correct because reset was done for mdio bus to operate and it was in this case used for different purpose which was eth phy reset. With ethernet-phy-id phy reset happens only for the phy via phy framework.
