Ah, so it's that way... I don't think that is correct. What you're doing
here is assigning an SoC clock output pin pinctrl node to pinctrl property
of an image sensor device that is external to an SoC. Why don't you put
this pinctrl properties in the common "camera" node ?

Shouldn't it be "samsung,exynos5-is" (Imaging Subsystem), or something
more relevant to exynos5 ? Or what would be reasons to use "fimc" for
exynos5 ?
