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").
