This causes trouble on some userspace stacks that then try to re-scale these coordinates back to the framebuffer resolution, like QT does. Use the of_touchscreen code to find the real touchscreen limits in the DT case, and report that to the userspace. Thanks, Maxime Changes from v1: - Do not use input_set_abs_params anymore to avoid enabling an axis that was not enabled by the driver itself in of_touchscreen - Emit a warning when an axis is set in the DT but not enabled in the driver - Remove EV_SYN from the edt-ft5x06 driver Maxime Ripard (4): input: touchscreen: of: Use input_set_abs_params input: touchscreen: of: Register multitouch axes input: ft5x06: Allow to set the maximum axes value through the DT input: edt-ft5x06: Remove EV_SYN event report drivers/input/touchscreen/edt-ft5x06.c | 6 ++- drivers/input/touchscreen/of_touchscreen.c | 62 +++++++++++++++++++++++++----- 2 files changed, 57 insertions(+), 11 deletions(-) -- 2.1.1
