[PATCH v5 0/4] Add initial configfs support for IIO

[Daniel Baluta]

This patchset introduces IIO software triggers, offers a way of configuring
them via configfs and adds the IIO hrtimer based interrupt source to be used
with software triggers.

The arhitecture is now split in 3 parts, to remove all IIO trigger specific
parts from IIO configfs core:

(1) IIO software triggers - are independent of configfs.
(2) IIO configfs - offers a generic way of creating IIO objects. So far we can
	create software triggers.
(3) IIO hrtimer trigger - is the first interrupt source for software triggers
	(with syfs to follow). Each trigger type can implement its own set of
	attributes.

Changes since v4:
	* patch 1/4
		- fixed "new line" nit in industrialio-sw-trigger.c
		- added license header in sw_trigger.h
	* patch 2/4
		- none
	* patch 3/4 
		- none
	* patch 4/4
		- removed "Further work" chapter in iio_configfs.txt
		- added configfs-iio file in Documentation/ABI/testing

Changes since v3:
	* addressed comments from Jonathan for previous version
	* https://lkml.org/lkml/2015/4/6/111
