Mark Pearson 2fd003ee8a Input: synaptics - disable Intertouch for Lenovo T14 and P14s AMD G1 
Since intertouch was enabled for the T14 and P14s AMD G1 laptops there
have been a number of reports of touchpads not working well.

Debugging this with Synaptics they noted that intertouch should not be
enabled as SMBUS host notify is not available on these laptops.

Reverting the previous commit (e4ce4d3a93)
to restore functionality back to what it was.

Note - we are working with Synaptics to see if there is a better
solution, but nothing is confirmed as yet.

Lyude Paul 7984b43542 Input: synaptics - enable InterTouch for the ThinkPad P1 G3 
Noticed this while trying to debug some unrelated issues: this laptop has
the ability to use rmi4 but doesn't by default. So let's fix that.

Tested locally, including mouse buttons, on my ThinkPad P1 G3. This might
also enable the X1 Extreme G3, but I don't have such a system to test
locally (presumably Mark can chime in if that's the case).

Follow the advice of the below link and prefer 'strscpy' in this
subsystem. Conversion is 1:1 because the return value is not used.

Matthew Haughton e4ce4d3a93 Input: synaptics - enable InterTouch on ThinkPad T14/P14s Gen 1 AMD 
Confirmed LEN2064 on my P14s works with psmouse.synaptics_intertouch=1
By all accounts T14 and P14s are the same hardware which only differ by
model identifier.

Dennis Kadioglu 642aa86eaf Input: synaptics - add a second working PNP_ID for Lenovo T470s 
The Lenovo Thinkpad T470s I own has a different touchpad with "LEN007a"
instead of the already included PNP ID "LEN006c". However, my touchpad
seems to work well without any problems using RMI. So this patch adds the
other PNP ID.

Yussuf Khalil 1369d0abe4 Input: synaptics - enable RMI on HP Envy 13-ad105ng 
This laptop (and perhaps other variants of the same model) reports an
SMBus-capable Synaptics touchpad. Everything (including suspend and
resume) works fine when RMI is enabled via the kernel command line, so
let's add it to the whitelist.

Benjamin Tissoires 5179a9dfa9 Input: synaptics - remove the LEN0049 dmi id from topbuttonpad list 
The Yoga 11e is using LEN0049, but it doesn't have a trackstick.

Thus, there is no need to create a software top buttons row.

However, it seems that the device works under SMBus, so keep it as part
of the smbus_pnp_ids.

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.
