Subject: [PATCH 5/5] arm64: dts: sprd: Add one suspend timer
Date: Mon, 23 Jul 2018 14:10:20 +0800 [thread overview]
Message-ID: <daf81b1cc8dd6048a9fcb7682a5937b72eb46dfd.1531881619.git.baolin.wang@linaro.org> (raw)
In-Reply-To: <2531014d066e61063b3d7906e6df55caa028e17c.1531881619.git.baolin.wang@linaro.org>

On Spreadtrum platform, the current clocksource for timekeeping will be
stopped in suspend state, thus add one always-on timer to calculate the
suspend time.
