Subject: [PATCH v2 2/2] ARM: dts: imx6q-marsboard: properly define rgmii PHY
Date: Fri, 13 Mar 2020 06:32:24 +0100 [thread overview]
Message-ID: <20200313053224.8172-3-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20200313053224.8172-1-o.rempel@pengutronix.de>
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.
