This patch serie is to be applied on top of https://patchwork.kernel.org/project/linux-iio/list/?series=147 (a more recent version of the serie is available here : https://gitlab.com/vilhelmgray/iio/tree/generic_counter_v10 ) Main changes in v2: The code is a bit simpler, thanks to more use of devm_* functions. The polling/32bit signed version has been dropped, as not needed and no other driver is doing that.
