Subject: [PATCH 18/19] clocksource: mips-gic: Use clockevents_config_and_register
Date: Mon, 20 Oct 2014 12:04:05 -0700 [thread overview]
Message-ID: <1413831846-32100-19-git-send-email-abrestic@chromium.org> (raw)
In-Reply-To: <1413831846-32100-1-git-send-email-abrestic@chromium.org>
Use clockevents_config_and_register to setup the clock_event_device
based on frequency and min/max ticks instead of doing it ourselves.
