Both. :-) You can come up with some names and attributes that are common across devices, and those should be leveraged when possible. But, I don't think it's possible, or worthwhile, to try to map every device state to a common, generic (i.e. limited) vocabulary. You want drivers to export the states that they know about, in the format that makes the most to them (e.g. PCI D0-D3), instead of having them scratch their head about what to name the states. >From that point (when they're exported), it's pretty simple to condense the vocbulary into something that makes more sense for the platform (like, "on", "off", "more off", etc).
