Subject: [PATCH v3 2/2] arm64: dts: allwinner: a64: Enable A64 timer workaround
Date: Sat, 12 Jan 2019 20:17:19 -0600 [thread overview]
Message-ID: <20190113021719.46457-3-samuel@sholland.org> (raw)
In-Reply-To: <20190113021719.46457-1-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.
Acked-by: Maxime Ripard <maxime.ripard@bootlin.com>
