Subject: [PATCH 04/11] clocksource: sun5i: Remove sched_clock
Date: Mon, 30 Mar 2015 22:17:06 +0200	[thread overview]
Message-ID: <1427746633-9137-4-git-send-email-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <1427746633-9137-1-git-send-email-daniel.lezcano@linaro.org>

From: Maxime Ripard <maxime.ripard@free-electrons.com>

It's not possible to remove a sched_clock once it has been added, nor is it
possible to change its rate.

Since we will need to support a rate change, and that we have other
sched_clocks in the system anyway, remove it.
