Subject: [PATCH] ARM: dts: Specify default clocks for Exynos4 FIMC devices
Date: Wed, 10 Sep 2014 18:37:34 +0200	[thread overview]
Message-ID: <1410367054-30926-1-git-send-email-s.nawrocki@samsung.com> (raw)

The default mux and divider clocks are specified in device tree
so that the FIMC devices in Exynos4210 and Exynos4x12 SoCs are
clocked from recommended clock source and with maximum supported
frequency. If needed these settings could be overrode in board
specific dts files, however they are in practice optimal in most
cases.
