From 05767707a8bb9c869346149c873cfc2320493651 Mon Sep 17 00:00:00 2001 From: Hannes Schmelzer Date: Fri, 13 Dec 2019 08:12:45 +0100 Subject: dts: am335x-brsmarc1/xre1: insert phy_id again commit 3b3e8a37d36e ("arm: dts: am335x: sync cpsw/mdio/phy with latest linux - drop phy_id") did sync with recent linux kernel and replaced therefore the 'phy_id' property with a phy-handle pointing to the mdio. This is OK for linux, but introduces trouble with the already running vxWorks on this target. So this commit here re-inerts the phy_id property beside the phy-handle property to be compatible with both.
