commit abbe3acd7d72ab4633ade6bd24e8306b67e0add3 upstream.

Thinkpad t480 laptops had some touchpad features disabled, resulting in the
loss of pinch to activities in GNOME, on wayland, and other touch gestures
being slower. This patch adds the touchpad of the t480 to the smbus_pnp_ids
whitelist to enable the extra features. In my testing this does not break
suspend (on fedora, with wayland, and GNOME, using the rc-6 kernel), while
also fixing the feature on a T480.

commit 9843f3e08e2144724be7148e08d77a195dea257a upstream.

They are capable of using intertouch and it works well with
psmouse.synaptics_intertouch=1, so add them to the list.

Without it, scrolling and gestures are jumpy, three-finger pinch gesture
doesn't work and three- or four-finger swipes sometimes get stuck.

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.

"Acer Aspire F5-573G is MS Precision touchpad which should use hid

[ 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:
