This was achieved by duplicating the PMU node as its child like: soc@0 { system-controller@10020000 { ... }; // Real PMU camera@11800000 { fimc-is@12000000 { // FIMC IS camera node pmu@10020000 { reg = <0x10020000 0x3000>; // Fake PMU node }; }; }; }; 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.
