Subject: [PATCH v3 4/7] arm64: tegra: Add native timer support on Tegra186
Date: Fri, 3 Apr 2020 22:22:06 +0200 [thread overview]
Message-ID: <20200403202209.299823-5-thierry.reding@gmail.com> (raw)
In-Reply-To: <20200403202209.299823-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
The native timers IP block found on NVIDIA Tegra SoCs implements a
watchdog timer that can be used to recover from system hangs. Add the
device tree node on Tegra186.
