Subject: [PATCH 5/6] arm64: tegra: Enable native timers on Tegra194
Date: Thu, 14 Apr 2022 13:55:37 +0530 [thread overview]
Message-ID: <1649924738-17990-6-git-send-email-kkartik@nvidia.com> (raw)
In-Reply-To: <1649924738-17990-1-git-send-email-kkartik@nvidia.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 and
enable the device tree node on Tegra194.
