Subject: [PATCH v3 3/5] clocksource: sun5i: Remove sched_clock
Date: Thu, 5 Mar 2015 11:20:54 +0100 [thread overview]
Message-ID: <1425550856-12928-4-git-send-email-maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <1425550856-12928-1-git-send-email-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.
