Devicetree for the FIMC IS camera included duplicated PMU node as its child. This is not a correct representation of the hardware. Mapping the PMU (Power Management Unit) IO memory should be via syscon-like phandle (samsung,pmu-syscon, already used for other drivers), not by duplicating "pmu" Devicetree node inside the FIMC IS. The change is not compatible with older Linux kernel, which does not parse samsung,pmu-syscon property.
