Subject[PATCH 1/2] ARM: dts: samsung: exynos4x12: replace duplicate pmu node with phandle
Date
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.
