2017-10-19iio: make function argument and some structures constBhumika Goyal1-1/+1
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.

2017-03-13iio: sw-device: Fix config group initializationLars-Peter Clausen1-1/+1
Use the IS_ENABLED() helper macro to ensure that the configfs group is initialized either when configfs is built-in or when configfs is built as a module. Otherwise software device creation will result in undefined behaviour when configfs is built as a module since the configfs group for the device not properly initialized. Similar to commit b2f0c09664b7 ("iio: sw-trigger: Fix config group initialization").

2016-05-04iio: Add support for creating IIO devices via configfsDaniel Baluta1-0/+70
This is similar with support for creating triggers via configfs. Devices will be hosted under: * /config/iio/devices We allow users to register "device types" under: * /config/iio/devices/<device_types>/ Signed-off-by: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
