Subject: [PATCH 4/5] arm64: dts: qcom: ipq5018: add MDIO buses

From: George Moussalem <george.moussalem@...look.com>

IPQ5018 contains two mdio buses of which one bus is used to control the
SoC's internal GE PHY, while the other bus is connected to external PHYs
or switches.

There's already support for IPQ5018 in the mdio-ipq4019 driver, so let's
simply add the mdio nodes for them.
