    Ahhh, of course. What a cunning hiding place! :-)

    However it doesn't suit my need - I want something more abstracted.

    I can see there may well be a place for a simple on/off switch for some
    components, but then I would prefer to see it as

    /sys/class/power-switch/$devicename/state

    rather than

    /sys/devices/platform/reg-userspace-consumer.X/{name,state}


    Thanks,
