Subject: [PATCH v3 10/11] ARM: Exynos: use fin_pll clock as the tick clock source for mct
Date: Thu, 15 Nov 2012 03:37:32 +0530	[thread overview]
Message-ID: <1352930853-12268-11-git-send-email-thomas.abraham@linaro.org> (raw)
In-Reply-To: <1352930853-12268-1-git-send-email-thomas.abraham@linaro.org>

With the migration of Exynos4 clocks to use common clock framework, the old
styled 'xtal' clock is not used anymore. Instead, the clock 'fin_pll' is used
as the tick clock for mct controller.
