Subject: [PATCH 3/6] clocksource/drivers/timer-tegra186: Add support for Tegra234 SoC
Date: Thu, 14 Apr 2022 13:55:35 +0530 [thread overview]
Message-ID: <1649924738-17990-4-git-send-email-kkartik@nvidia.com> (raw)
In-Reply-To: <1649924738-17990-1-git-send-email-kkartik@nvidia.com>
The timer IP block present on Tegra234 SoC supports watchdog timer
functionality that can be used to recover from system hangs. The
watchdog timer uses a timer in the background for countdown.
