All of these are highly generic and should *not* be passed through
from user space to the driver directly but rather be properly
abstracted as Roopa proposed. The value of this API is abstraction.
If we introduce per device attributes for generic functions we lose
large portions of the value gained.

You mentioned you have additional attributes in mind, maybe you can
give a few examples which are not generic, i.e. do not apply to
multiple vendors.
