Hello to all, For those who are receiving this email for the second time, it seems that linux-iio@xxxxxxxxxxxxxxx, doesn't accept HTML format emails, so this is a plain text version. I have been developing a linux kernel drive for a DAC converter, ad5766 and it supports changing the output span range, from eight available output ranges during runtime. This is done setting scale and offset attributes trough a `write_raw` call. When changing the range during runtime for this chip, a software reset is necessary, before writing to the span register. Do you think this is acceptable upstream? Should we make the span ranges selectable at runtime? From what I heard, it's not always a good idea to do reset of a device at runtime.
