Kernel wishlist item: Better IIO API

[Bastien Nocera <hadess@hadess.net>]

Hey,

I've posted this a couple of days ago:
http://www.hadess.net/2014/10/a-gnome-kernel-wishlist.html
along with a mail to LKML:
http://thread.gmane.org/gmane.linux.kernel/1810083

I've recently added to my list an item about IIO:
https://wiki.gnome.org/BastienNocera/KernelWishlist

Are there any plans for a better API for the IIO subsystem? The API
might be good enough to drive from shell scripts, or helpers that only
need to work with one variant of a device, but my attempts at trying to
use the IIO subsystem to provide an accelerometer to do automatic
display rotation[1] showed that the API is really cumbersome.

The code I wrote spends most of its time creating sysfs paths, reading
values in different formats, and mangling filenames[2].

Is an ioctl-based API planned? Something where I could get/set
structures to gather metadata about the device, and set it up easily, so
reading data from it is easier?

Cheers

PS: I plan on updating my Kionix driver posted here:
http://thread.gmane.org/gmane.linux.kernel.iio/13793
once I've had the opportunity to double-check it works with the
aforementioned code.
