Subject: [PATCH 06/93] clocksource/drivers/rockchip: Add the dynamic irq flag to the timer
Date: Thu,  7 Jul 2016 10:00:39 +0200	[thread overview]
Message-ID: <1467878526-1238-6-git-send-email-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <1467878526-1238-1-git-send-email-daniel.lezcano@linaro.org>

From: "Huang, Tao" <huangtao@rock-chips.com>

The rockchip timer is a broadcast timer. Add the CLOCK_EVT_FEAT_DYNIRQ flag
and set the cpumask to all possible cpus to save power by avoiding
unnecessary wakeups and IPIs.
