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

2019-02-20T09:25:47+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.

Revert "Input: elan_i2c - add ACPI ID for touchpad in ASUS Aspire F5-573G"

2019-02-20T09:25:44+00:00

commit f420c54e4b12c1361c6ed313002ee7bd7ac58362 upstream.

This reverts commit 7db54c89f0b30a101584e09d3729144e6170059d as it
breaks Acer Aspire V-371 and other devices. According to Elan:

"Acer Aspire F5-573G is MS Precision touchpad which should use hid
 multitouch driver. ELAN0501 should not be added in elan_i2c."

Input: synaptics - enable SMBus for HP EliteBook 840 G4

2019-01-13T08:51:03+00:00

[ Upstream commit 7a71712293ba303aad928f580b89addb0be2892e ]

dmesg reports that "Your touchpad (PNP: SYN3052 SYN0100 SYN0002 PNP0f13)
says it can support a different bus."

I've tested the offered psmouse.synaptics_intertouch=1 with 4.18.x and
4.19.x and it seems to work well. No problems seen with suspend/resume.

Also, it appears that RMI/SMBus mode is actually required for 3-4 finger
multitouch gestures to work -- otherwise they are not reported at all.

Information from dmesg in both modes:

Input: synaptics - enable RMI on ThinkPad T560

2019-01-13T08:50:58+00:00

[ Upstream commit ca5047286c9c93a01e1f471d00a6019536992954 ]

Before commit 7fd6d98b89f3 ("i2c: i801: Allow ACPI AML access I/O
ports not reserved for SMBus"), enabling RMI on the T560 would cause
the touchpad to stop working after resuming from suspend. Now that
this issue is fixed, RMI can be enabled safely and works fine.

Input: elantech - disable elan-i2c for P52 and P72

2018-12-29T12:37:59+00:00

commit d21ff5d7f8c397261e095393a1a8e199934720bc upstream.

The current implementation of elan_i2c is known to not support those
2 laptops.

A proper fix is to tweak both elantech and elan_i2c to transmit the
correct information from PS/2, which would make a bad candidate for
stable.

So to give us some time for fixing the root of the problem, disable
elan_i2c for the devices we know are not behaving properly.
