Now that 'poweroff' node is available in exynos850.dtsi, 'poweroff' command can be enabled. Although it only turns the SoC off, it still can be useful for testing purposes and experiments with power consumption. The corresponding Linux kernel commit [1] mentions that overall board current consumption goes from ~60 mA down to few mA after issuing poweroff command.
