Subject: [PATCH 2/4] arm64: dts: rockchip: Arch counter doesn't tick in system suspend
Date: Tue, 22 Nov 2016 10:44:22 +0100	[thread overview]
Message-ID: <1479807866-6957-2-git-send-email-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <1479807866-6957-1-git-send-email-daniel.lezcano@linaro.org>

From: Brian Norris <briannorris@chromium.org>

The "arm,no-tick-in-suspend" property was introduced to note
implementations where the system counter does not quite follow the ARM
specification that it "must be implemented in an always-on power
domain".

Particularly, RK3399's counter stops ticking when we switch from the
24MHz clock to the 32KHz clock in low-power suspend, so let's mark it as
such.
