Subject: [PATCH 2/2] arm64: tegra: Make the RTC a wakeup source on Jetson TX2
Date: Fri, 17 Apr 2020 19:11:17 +0200 [thread overview]
Message-ID: <20200417171117.2556374-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20200417171117.2556374-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
The RTC found on the MAX77620 PMIC can be used as a wakeup source on
Jetson TX2, which is useful to wake the system from suspend at a given
time.
