Input: i8042 - add Entroware Proteus EL07R4 to nomux and reset lists

2020-09-23T10:11:01+00:00

commit c4440b8a457779adeec42c5e181cb4016f19ce0f upstream.

The keyboard drops keypresses early during boot unless both the nomux
and reset quirks are set. Add DMI table entries for this.

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

2020-08-26T08:31:01+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

2020-08-21T09:05:37+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.

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

Input: i8042 - add Lenovo XiaoXin Air 12 to i8042 nomux list

2020-07-22T07:32:11+00:00

commit 17d51429da722cd8fc77a365a112f008abf4f8b3 upstream.

This fixes two finger trackpad scroll on the Lenovo XiaoXin Air 12.
Without nomux, the trackpad behaves as if only one finger is present and
moves the cursor when trying to scroll.

Input: mms114 - add extra compatible for mms345l

2020-07-22T07:32:04+00:00

[ Upstream commit 7842087b0196d674ed877d768de8f2a34d7fdc53 ]

MMS345L is another first generation touch screen from Melfas,
which uses mostly the same registers as MMS152.

However, there is some garbage printed during initialization.
Apparently MMS345L does not have the MMS152_COMPAT_GROUP register
that is read+printed during initialization.

  TSP FW Rev: bootloader 0x6 / core 0x26 / config 0x26, Compat group: \x06

On earlier kernel versions the compat group was actually printed as
an ASCII control character, seems like it gets escaped now.

But we probably shouldn't print something from a random register.

Add a separate "melfas,mms345l" compatible that avoids reading
from the MMS152_COMPAT_GROUP register. This might also help in case
there is some other device-specific quirk in the future.

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: mms114 - fix handling of mms345l

2020-06-22T07:04:59+00:00

[ Upstream commit 3f8f770575d911c989043d8f0fb8dec96360c41c ]

MMS345L is another first generation touch screen from Melfas,
which uses the same registers as MMS152.

However, using I2C_M_NOSTART for it causes errors when reading:

	i2c i2c-0: sendbytes: NAK bailout.
	mms114 0-0048: __mms114_read_reg: i2c transfer failed (-5)

The driver works fine as soon as I2C_M_NOSTART is removed.
