I am reworking the series and dropped this patch. I think it got added because the driver currently mixes up sometimes some of the Y & Z coordinates. So I check how it behaves and if required I try to push to tslib if still required. I doubt someone is using this directly on the eventX node. >FWIW I have been asking this question from the very beginning of this >driver being submitted. I'm sorry. I'm currently trying to get the three pieces of the driver (mfd, touch, iio) into shape. If there is anything please let me know. Sebastian
