This is not the case and each thermal zone has its own governor instance acting individually without collaboration with other governors. As the cooling device for the CPU and the GPU thermal zones is the same, each governors take different decisions for the same cooling device leading to conflicting instructions and an erratic behavior. As the cooling-maps is about to become an optional property, let's remove the cpu cooling device map from the GPU thermal zone.
