Subject: [PATCH 06/13] clocksource: vf_pit_timer: Support shutdown mode
Date: Mon, 29 Sep 2014 02:23:39 +0200 [thread overview]
Message-ID: <1411950226-21598-6-git-send-email-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <1411950226-21598-1-git-send-email-daniel.lezcano@linaro.org>
From: Stefan Agner <stefan@agner.ch>
In order to avoid waking up the system in a low power mode, the
clocksource should not generate interrupts anymore. Disable the PIT
timer interrupt when changing into the CLOCK_EVT_MODE_SHUTDOWN mode.
[dlezcano] : remove superfluous empty line
