Input: synaptics - enable InterTouch on ThinkPad T14/P14s Gen 1 AMD

2022-03-21T04:59:45+00:00

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.

Input: synaptics - enable InterTouch for ThinkPad P1/X1E gen 2

2020-10-05T02:51:46+00:00

With the new RMI4 F3A support, we're now able to enable full RMI4
support for this model. We also tidy up the comments a bit, as the X1E
is essentially the same computer as the P1.

Input: synaptics-rmi4 - rename f30_data to gpio_data

2020-10-05T02:51:43+00:00

f30_data in rmi_device_platform_data could be also referenced by RMI
function 3A, so rename it and the structure name to avoid confusion.

Input: synaptics - enable InterTouch for ThinkPad X1E 1st gen

Tested on my own laptop, touchpad feels slightly more responsive with
this on, though it might just be placebo.

Input: synaptics - add a second working PNP_ID for Lenovo T470s

2020-05-27T06:11:28+00:00

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.

Input: synaptics - enable RMI on HP Envy 13-ad105ng

2020-03-24T22:23:52+00:00

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.

Input: synaptics - remove the LEN0049 dmi id from topbuttonpad list

2020-02-14T01:09:49+00:00

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.
