Input: elantech - add Fujitsu Lifebook E556 to force crc_enabled

2016-10-07T23:30:12+00:00

Another Lifebook machine that needs the same quirk as other similar models to make the driver working. Also let's reorder elantech_dmi_force_crc_enabled list so LIfebook enries are in alphabetical order.

Input: elantech - force needed quirks on Fujitsu H760

2016-10-04T00:31:57+00:00

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.

Input: elantech - add more IC body types to the list

The touchpad in HP Pavilion 14-ab057ca reports it's version as 12 and according to Elan both 11 and 12 are valid IC types and should be identified as hw_version 4. Reported-by: Patrick Lessard Tested-by: Patrick Lessard Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov

Input: psmouse - use same format for secondary devices as for primary

2016-06-19T00:39:23+00:00

This patch changes name of secondary psmouse devices to mach format of primary device. Format of primary device is "protocol vendor name" and is set by function psmouse_switch_protocol() in file psmouse-base.c. Signed-off-by: Pali Rohár Signed-off-by: Dmitry Torokhov

Input: elantech - mark protocols v2 and v3 as semi-mt

2016-01-12T01:45:32+00:00

When using a protocol v2 or v3 hardware, elantech uses the function elantech_report_semi_mt_data() to report data. This devices are rather creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid touch is reported. Anyway, userspace (libinput) is now confused by these (0,0) touches, and detect them as palm, and rejects them. Commit 3c0213d17a09 ("Input: elantech - fix semi-mt protocol for v3 HW") was sufficient enough for xf86-input-synaptics and libinput before it has palm rejection. Now we need to actually tell libinput that this device is a semi-mt one and it should not rely on the actual values of the 2 touches.
