Subject: [PATCH 2/2] arm64: dts: allwinner: a64: Enable A64 timer workaround
Date: Thu, 10 May 2018 21:27:51 -0500 [thread overview]
Message-ID: <20180511022751.9096-3-samuel@sholland.org> (raw)
In-Reply-To: <20180511022751.9096-1-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.
