In most of the cases I'm thinking of, it wouldn't be a user requesting a
state but rather software (say, a cell phone progressively entering
lower power states due to inactivity). I haven't noticed a platform
with more than 3 low-power modes so far, but I'm sure it'll happen soon.
If the time isn't right for incompatible changes to these interfaces
then I guess mapping standby and mem to platform-specific things will
work for now, maybe with some tweak to allow a choice of actual state
entered. At some more opportune time in the future I'll suggest an
attribute that allows a choice of platform-specific method of
suspend-to-mem, somewhat like the "disk" attribute for suspend-to-disk.
Thanks,
