From c006ec838414d910bdd63ba8d919e602425e194e Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 8 Sep 2013 14:57:00 +0100 Subject: iio: add info_mask_[shared_by_dir/shared_by_all] These two additional info_mask bitmaps should allow all 'standard' numeric attributes to be handled using the read_raw and write_raw callbacks. Whilst this should reduce code, the more important element is that this makes these values easily accessible to in kernel users of IIO devices.
