I suspect these modes are something else. I'm looking at the mma8452 driver, and it also has "active" "standby" and "sleep" modes, but I'm talking about different *power* (oversampling) configurations in "active" mode, which is what said sysfs file is about.
But yes, it should be potenially uniform across sensors, which is why I would probably only add "normal" to the list. At least I can imagine that many devices have an oversampling mode called "normal".
A simple user interface is important so right now I think the best is to leave it as it is, and not to add complexity and every possible option for the user.
