Input: psmouse - add a newline when printing 'proto' by sysfs

2020-08-26T08:40:55+00:00

[ Upstream commit 4aec14de3a15cf9789a0e19c847f164776f49473 ]

When I cat parameter 'proto' by sysfs, it displays as follows. It's
better to add a newline for easy reading.

Input: sentelic - fix error return when fsp_reg_write fails

2020-08-21T11:05:36+00:00

[ Upstream commit ea38f06e0291986eb93beb6d61fd413607a30ca4 ]

Currently when the call to fsp_reg_write fails -EIO is not being returned
because the count is being returned instead of the return value in retval.
Fix this by returning the value in retval instead of count.

Input: elan_i2c - only increment wakeup count on touch

2020-07-29T08:18:38+00:00

[ Upstream commit 966334dfc472bdfa67bed864842943b19755d192 ]

This moves the wakeup increment for elan devices to the touch report.
This prevents the drivers from incorrectly reporting a wakeup when the
resume callback resets then device, which causes an interrupt to
occur.

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

[ 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

2020-06-17T14:40:21+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

2020-04-01T09:01:57+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

2020-02-19T18:52:55+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

commit bf502391353b928e63096127e5fd8482080203f5 upstream.

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

Some Lenovo X1 Carbon Gen 6 laptops report LEN0091. Add this
