Input: stmpe - add axis inversion and swapping capability
Make use of generic touchscreen_properties structure to add axis inversion and swapping capabilities. It's configurable via devicetree properties: touchscreen-inverted-x touchscreen-inverted-y touchscreen-swapped-x-y Signed-off-by: Stefan Riedmueller <s.riedmueller@phytec.de> Link: https://lore.kernel.org/r/20200922093903.157232-1-s.riedmueller@phytec.de Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
