Ah, this makes sense. The only issue is:

static int add_regulator_attributes(struct regulator_dev *rdev)
...
	if ((ops->get_voltage && ops->get_voltage(rdev) >= 0) ||
	    (ops->get_voltage_sel && ops->get_voltage_sel(rdev) >= 0)) {
		status = device_create_file(dev, &dev_attr_microvolts);

so the microvolts file doesn't get created.
