    sysfs is relevant for bigger systems but for small embedded stuff the whole
    PM layer is fairly "so what". At that level your hardware is tightly defined
    and you *know* the power management ordering. Policy becomes critical for
    performance and gets done at a very fine grained level - things like waking
    up the flash for a read then turning it back off on a timer for example.
