Subject: [PATCH 7/9] ARM: dts: sun9i: Add A80 GMAC RGMII pinmux setting
Date: Wed, 6 Feb 2019 11:32:37 +0800 [thread overview]
Message-ID: <20190206033239.3619-8-wens@csie.org> (raw)
In-Reply-To: <20190206033239.3619-1-wens@csie.org>
The GMAC (gigabit ethernet controller) supports RGMII to connect to
the ethernet PHY, for gigabit network speeds.
