Bhumika Goyal	612a462acb	iio: make function argument and some structures const ... Make the argument of the functions iio_sw{d/t}_group_init_type_name const as they are only passed to the function config_group_init_type_name having the argument as const. Make the config_item_type structures const as they are either passed to the functions having the argument as const or they are stored in the const "ci_type" field of a config_item structure.

Jonathan Cameron	8d6c16dd72	iio:configfs: Introduce iio/configfs.h to provide a location for the configfs_subsystem ... This exported element needs to be accesible to all drivers using configfs within IIO. Previously it was in the sw_trig.h file which only convered one such usecase. This also fixes a sparse warning as it is now in a header that makes sense to include from industrialio-configfs.c Signed-off-by: Jonathan Cameron < jic23@kernel.org>	2015-12-05 16:25:30 +00:00
Daniel Baluta	8261d961d1	iio: core: Introduce IIO configfs support ... This patch creates the IIO configfs root group. The group will appear under <mount-point>/iio/, usually /config/iio. We introduce configfs support in IIO in order to be able to easily create IIO objects from userspace. The first supported IIO objects are triggers introduced with next patches.
