Subject: [PATCH v2 2/2] arm64: dts: allwinner: a64: Enable A64 timer workaround
Date: Wed, 11 Jul 2018 21:25:15 -0500	[thread overview]
Message-ID: <20180712022515.7255-3-samuel@sholland.org> (raw)
In-Reply-To: <20180712022515.7255-1-samuel@sholland.org>

As instability in the architectural timer has been observed on multiple
devices using this SoC, inluding the Pine64 and the Orange Pi Win,
enable the workaround in the SoC's device tree.
