On devices with a native portrait screen a landscape touchscreen / digitizer may be used, this happens e.g. on ebook readers. In this case the X and Y axis of the touchscreen are swapped compared to the screen. Add a touchscreen-swap-x-y property which drivers can use to see if they need to swap the axis to make the touchscreen coordinates match the screen coordinates.
