Subject: [PATCH RFC V2 6/6] ARM: dts: bcm2711-rpi-4: Enable GENET support
Date: Sat,  2 Nov 2019 14:41:33 +0100	[thread overview]
Message-ID: <1572702093-18261-7-git-send-email-wahrenst@gmx.net> (raw)
In-Reply-To: <1572702093-18261-1-git-send-email-wahrenst@gmx.net>

This enables the Gigabit Ethernet support on the Raspberry Pi 4.
The defined PHY mode is equivalent to the default register settings
in the downstream tree.
