Input: psmouse - fix build error of multiple definition

2019-10-31T22:15:05+00:00

commit 49e6979e7e92cf496105b5636f1df0ac17c159c0 upstream. trackpoint_detect() should be static inline while CONFIG_MOUSE_PS2_TRACKPOINT is not set, otherwise, we build fails: drivers/input/mouse/alps.o: In function `trackpoint_detect': alps.c:(.text+0x8e00): multiple definition of `trackpoint_detect' drivers/input/mouse/psmouse-base.o:psmouse-base.c:(.text+0x1b50): first defined here Reported-by: Hulk Robot Fixes: 55e3d9224b60 ("Input: psmouse - allow disabing certain protocol extensions") Signed-off-by: YueHaibing Signed-off-by: Dmitry Torokhov Signed-off-by: Ben Hutchings

Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780

2019-05-02T20:41:50+00:00

commit e8b22d0a329f0fb5c7ef95406872d268f01ee3b1 upstream. Like Fujitsu CELSIUS H760, the H780 also has a three-button Elantech touchpad, but the driver needs to be told so to enable the middle touchpad button. The elantech_dmi_force_crc_enabled quirk was not necessary with the H780. Also document the fw_version and caps values detected for both H760 and H780 models.

Input: elantech - force needed quirks on Fujitsu H760

2019-05-02T20:41:50+00:00

commit f9a703a54d16ba2470391c4b12236ee56591d50c upstream. Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with the same quirks. Without this patch, the touchpad is useless out-of-the-box as the mouse pointer won't move. This patch makes the driver aware of both the crc_enabled=1 requirement and the middle button, making the touchpad fully functional out-of-the-box.

commit e0ae2519ca004a628fa55aeef969c37edce522d3 upstream. Some touchpad has middle key and it will be indicated in bit 2 of packet[0]. We need to fix V4 formation's byte mask to prevent error decoding. Signed-off-by: KT Liao Signed-off-by: Dmitry Torokhov Signed-off-by: Ben Hutchings

commit 24bb555e6e46d96e2a954aa0295029a81cc9bbaa upstream. PNPID is better way to identify the type of touchpads. Enable middle button support on 2 types of touchpads on Lenovo P52. Signed-off-by: Aaron Ma Reviewed-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov Signed-off-by: Ben Hutchings

Input: elantech - report the middle button of the touchpad

2018-11-20T18:05:23+00:00

commit f386474e12a560e005ec7899e78f51f6bdc3cf41 upstream. In the past, no elantech was known with 3 touchpad mouse buttons. Fujitsu H730 is the first known elantech with a middle button. This commit enables this middle button. For backwards compatibility, the Fujitsu is detected via DMI, and only for this one 3 buttons will be announced.

commit f5d07b9e98022d50720e38aa936fc11c67868ece upstream. Lenovo introduced trackpoint compatible sticks with minimum PS/2 commands. They supposed to reply with 0x02, 0x03, or 0x04 in response to the "Read Extended ID" command, so we would know not to try certain extended commands. Unfortunately even some trackpoints reporting the original IBM version (0x01 firmware 0x0e) now respond with incorrect data to the "Get Extended Buttons" command: thinkpad_acpi: ThinkPad BIOS R0DET87W (1.87 ), EC unknown thinkpad_acpi: Lenovo ThinkPad E470, model 20H1004SGE psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 0/0 Since there are no trackpoints without buttons, let's assume the trackpoint has 3 buttons when we get 0 response to the extended buttons query.

Input: trackpoint - assume 3 buttons when buttons detection fails

2018-03-03T15:52:27+00:00

commit 293b915fd9bebf33cdc906516fb28d54649a25ac upstream. Trackpoint buttons detection fails on ThinkPad 570 and 470 series, this makes the middle button of the trackpoint to not being recogized. As I don't believe there is any trackpoint with less than 3 buttons this patch just assumes three buttons when the extended button information read fails.
