Subject: [PATCH 2/2] arm64: tegra: Don't use architected timer for suspend on Tegra210
Date: Fri, 14 Jun 2019 12:52:37 +0200 [thread overview]
Message-ID: <20190614105237.20076-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20190614105237.20076-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Due to an integration issue the architected timer on Tegra210 does not
remain on during system suspend (a.k.a. SC7). Mark it accordingly so
that it isn't considered as a means to track suspend time.
