Subject: [PATCH v2 3/4] ARM: sa1100: provide OSTIMER0 clock for pxa_timer
Date: Tue, 2 Dec 2014 02:47:25 +0300 [thread overview]
Message-ID: <1417477646-14278-4-git-send-email-dbaryshkov@gmail.com> (raw)
In-Reply-To: <1417477646-14278-1-git-send-email-dbaryshkov@gmail.com>
Pxa_timer clocksource requires OSTIMER0 clock to be provided.
Add dummy clock returning proper rate.
