Subject: [PATCH] ARM: dts: Fix CLK_MOUT_CAMn parent clocks assignment for Trats2
Date: Fri, 16 Jan 2015 18:40:16 +0100	[thread overview]
Message-ID: <1421430016-32248-1-git-send-email-s.nawrocki@samsung.com> (raw)

In order to get exact 24MHz clock frequency value for the camera
sensor and avoid rounding errors the parent clock must be CLK_XUSBXTI,
not CLK_MOUT_MPLL_USER_T.  Currently the sensor's master clock
frequency is too high and the sensor doesn't work properly.

This fixes commit 0357a4438d531ef3cf529e80ffcd208eb8e35f55
("ARM: dts: Specify default clocks for Exynos4 camera devices").
