Subject[PATCH v2 3/3] ARM: dts: imx6qdl-icore: Add fec phy-handle
Date
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.
