Hello, this is v2 of my "Input: goodix - add axis swapping and axis inversion support" patchset. The goodix touchscreen driver has gained device-tree support in kernel 4.1, but doesn't currently support the touchscreen-swapped-x-y, touchscreen-inverted-x and touchscreen-inverted-y properties. On systems which combine a portrait-mode display with a landscape-mode touchscreen, such as e.g. the MSI Primo 81 tablet, support for these features is necessary to have the touchscreen and the display use the same coordinate system. With support for axis inversion, the "rotated_screen" flag in the driver can also be removed, as "rotated_screen" is just a special case of x/y axis inversion. This patchset sits on top of the "[PATCH v8 0/9] Goodix touchscreen enhancements" series by Irina Tirdea: https://www.spinics.net/lists/linux-input/msg41437.html I have successfully tested the axis swapping on an (arm-based) MSI Primo 81 tablet, but I lack appropriate hardware to do a real-world test of the "rotated_screen" code path, so I would appreciate very much if somebody with appropriate hardware (WinBook TW100 or TW700) could give it a try.
