Subject: [PATCH 5/6] clocksource: dw_apb_timer_of: Fix read_sched_clock
Date: Tue, 10 Dec 2013 20:16:11 +0100 [thread overview]
Message-ID: <1386702972-25565-5-git-send-email-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <1386702972-25565-1-git-send-email-daniel.lezcano@linaro.org>
From: Dinh Nguyen <dinguyen@altera.com>
The read_sched_clock should return the ~value because the clock is a
countdown implementation. read_sched_clock() should be the same as
__apbt_read_clocksource().
