in small chunks: 1. swap/flip 2. dejitter algorithms (allow to choose through DT) 3. integrate ADC (ambient light sensor) - maybe poll only if separate /dev/input is opened 4. /sys status interface (poll only if needed) unclear: fix for pressure

chunk 1 is done

chunk 2 is no longer needed (fuzz factor is good enough) and chunk 3/4 has been solved by iio. We only need to submit and discuss upstream.

Seems to work. But needs more review and it is not 100% clear if we should clip or report out of bounds coordinates. Android seems to expect the latter while X.org might get into problems. So we might have to remove the clipping feature (and convert some code to signed temporary variables).

Version 8 is for review on LKML and almost done...

Unfortunatly, maintainers did accept not all features. Especially not our really simple pre-calibration.
