I suspect > the scale is 1 and the offset is somewhere around 450mA though. Applied 1, 8 and 12 to the IIO togreg branch. I was waiting for some mess related to my tree to pan out upstream. Unfortunately that leaves us rather tight on timing for the coming merge window but hopefully Greg will take a last minute pull request for char-misc.
