Subject: [PATCH v2 1/2] ARM: dts: imx6dl-riotboard: properly define rgmii PHY
Date:   Fri, 13 Mar 2020 06:32:23 +0100
Message-Id: <20200313053224.8172-2-o.rempel@pengutronix.de>

Precedence: bulk

The Atheros AR8035 PHY can be autodetected but can't use interrupt
support provided on this board. Define MDIO bus and the PHY node to make
it work properly.
