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

2020-07-29T08:16:53+00:00

[ Upstream commit dcb00fc799dc03fd320e123e4c81b3278c763ea5 ]

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

2020-06-22T07:05:00+00:00

[ Upstream commit 642aa86eaf8f1e6fe894f20fd7f12f0db52ee03c ]

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

2020-04-02T13:28:16+00:00

commit 1369d0abe469fb4cdea8a5bce219d38cb857a658 upstream.

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

2020-02-19T18:51:53+00:00

commit 5179a9dfa9440c1781816e2c9a183d1d2512dc61 upstream.

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.

Input: synaptics - switch T470s to RMI4 by default

2020-02-19T18:51:53+00:00

commit bf502391353b928e63096127e5fd8482080203f5 upstream.

This supports RMI4 and everything seems to work, including the touchpad
buttons. So, let's enable this by default.

Input: synaptics - switch another X1 Carbon 6 to RMI/SMbus

commit fc1156f373e3927e0dcf06678906c367588bfdd6 upstream.

Some Lenovo X1 Carbon Gen 6 laptops report LEN0091. Add this
to the smbus_pnp_ids list.

Input: elan_i2c - remove Lenovo Legion Y7000 PnpID

2019-09-21T05:16:41+00:00

commit 0c043d70d04711fe6c380df9065fdc44192c49bf upstream.

Looks like the Bios of the Lenovo Legion Y7000 is using ELAN061B
when the actual device is supposed to be used with hid-multitouch.

Remove it from the list of the supported device, hoping that
no one will complain about the loss in functionality.

Revert "Input: elantech - enable SMBus on new (2018+) systems"

2019-09-06T10:40:02+00:00

This reverts commit 3d180fe5cd7625b67e0879ffa1f6ae1f09385485 which is
commit 883a2a80f79ca5c0c105605fafabd1f3df99b34c upstream.

This patch depends on an other series:
https://patchwork.kernel.org/project/linux-input/list/?series=122327&state=%2A&archive=both

It was a mistake to backport it in the v5.2 branch, as there
is a high chance we encounter a touchpad that needs the series
above.
