Subject: [PATCH v1 04/14] ARM: dts: imx6ull-colibri: add phy-supply to fec
Date:   Thu, 14 Apr 2022 10:50:56 +0200

From: Philippe Schenker <philippe.schenker@toradex.com>

This adds the proper phy-supply to the FEC. This supply is actually
switched by a clock that is now properly stated. This has the advantage
to add a delay for that particular regulator which is needed.
