What exactly is low power mode and how does it interact with the enable?
The name suggests it's a more efficient mode for use with low current
drain, is that right?

Those properties have awfully generic names and part of what I was
wondering above is if the low power mode maps onto the idle or standby
modes that the API defines? We don't cover those in the bindings yet
since they are unfortunately fuzzy but perhaps we need to do so.
