Subject: [PATCH v2 2/6] ARM: dts: sun8i: v40: bananapi-m2-berry: Enable GMAC ethernet controller
Date: Fri, 12 Apr 2019 07:33:01 -0300	[thread overview]
Message-ID: <1555065186-8154-3-git-send-email-pgreco@centosproject.org> (raw)
In-Reply-To: <1555065186-8154-1-git-send-email-pgreco@centosproject.org>

Just like the Bananapi M2 Ultra, the Bananapi M2 Berry has a Realtek
RTL8211E RGMII PHY tied to the GMAC.
The PMIC's DC1SW output provides power for the PHY, while the ALDO2
output provides I/O voltages on both sides.
