Subject: [PATCH v3 06/11] ARM: vexpress: use clocksource_of_init for sp804
Date: Wed, 13 Mar 2013 13:05:37 +0800 [thread overview]
Message-ID: <1363151142-32162-7-git-send-email-haojian.zhuang@linaro.org> (raw)
In-Reply-To: <1363151142-32162-1-git-send-email-haojian.zhuang@linaro.org>
Remove all code to parse sp804. Use clocksource_of_init() instead since
all these code are implemented in sp804 driver already.
