Subject: [PATCH v2 3/3] ARM: dts: imx6qdl-icore: Add fec phy-handle
Date: Mon, 30 Dec 2019 17:30:21 +0530 [thread overview]
Message-ID: <20191230120021.32630-3-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20191230120021.32630-1-jagan@amarulasolutions.com>
From: Michael Trimarchi <michael@amarulasolutions.com>
LAN8720 needs a reset of every clock enable. The reset needs
to be done at device level, due the flag PHY_RST_AFTER_CLK_EN.
So, add phy-handle by creating mdio child node inside fec.
This will eventually move the phy-reset-gpio which is defined
in fec node.
