Subject: [PATCH 3/3] arm64: allwinner: a64: dts: apply hack for RTL8211E on Pine64+
Date: Tue, 1 Oct 2019 16:29:12 +0800 [thread overview]
Message-ID: <20191001082912.12905-4-icenowy@aosc.io> (raw)
In-Reply-To: <20191001082912.12905-1-icenowy-h8G6r0blFSE@public.gmane.org>
Some of the Pine64+ boards are known to use a batch of broken RTL8211E
PHYs. A magic number that is in an undocumented field of a register is
passed from Realtek via Pine64.
Add the property to apply the hack to the Pine64+ device tree.
