Please change this attribute such that it accepts and reports strings
instead of numbers. This is more user-friendly and also will make shell
scripts that read from or write into this sysfs attribute much easier to
read. This will make this attribute follow the design philosophy of
self-documenting interfaces.

In new code, please order declarations from longest to shortest.

Also here, please order declarations from longest to shortest.

Thanks,
