[PATCH v2 1/9] ARM64: dts: meson-gxbb-odroidc2: add the ethernet PHY's reset GPIO

From: martin.blumenstingl@googlemail.com (Martin Blumenstingl)
Date: 2017-01-20 13:26:42
Also in: linux-amlogic, linux-devicetree
Subsystem: arm/amlogic meson soc support, the rest · Maintainers: Neil Armstrong, Kevin Hilman, Linus Torvalds

This resets the ethernet PHY during boot to get the PHY into a "clean"
state. While here also explicitly specify the phy-mode instead of
relying on the default-value from meson-gx.dtsi.
