Sadly not.  Hemanth contribute some thoughts on this when we were discussing
his cma3000 driver, but in the end for ease of merging, the sysfs bits were
dropped entirely.  Alan Cox has been posting a bma023 driver to linux-input
which has a totally device specific interface.  I suspect Dmitry will 
block that one on this basis so the discussion may well reopen. (I've just
written a reply to that suggesting that perhaps it should). Alan is
making some progress towards at least getting rid of some of the magic
numbers attributes in that driver.

Eric, are you happy to contribute on such a discussion?

As ever I'll approach it from what we have for IIO as we have a wider
range of device types than anyone else, but within reason I'm happy to
propose changes to IIO's interfaces as long as they don't break with
our requirements of generality, specificness and ease of understanding.
