Hello, 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 v6 0/9] Goodix touchscreen enhancements" series by Irina Tirdea: http://www.spinics.net/lists/linux-input/msg40992.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 apprechiate very much if somebody with appropriate hardware could give it a try. This is my first go at modifying an input driver; any kind of feedback and hints is welcome. Regards, Karsten Karsten Merker (2): Input: goodix - add dt axis swapping and axis inversion support Input: goodix - use "inverted_[xy]" flags instead of "rotated_screen" drivers/input/touchscreen/goodix.c | 31 ++++++++++++++++++++++++++----- 1 file changed, 26 insertions(+), 5 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
